update agent-lib

Root cause: The complex concatStringsSep command with power commands
(--power-shutdown, --power-reboot) and multiple --remember flags was
causing tuigreet to display its usage/flags instead of the login UI.
The quoting in the systemd binary paths may have been problematic.

Changes:
- Use lib.getExe instead of manual bin path for tuigreet
- Use simple 'Hyprland' command (found via PATH) instead of
  the full start-hyprland path which may have issues
- Remove unverified options: --remember-session, --remember-user-session,
  --user-menu, --user-menu-min-uid, --power-shutdown, --power-reboot
- Keep only verified options: --time, --remember, --asterisks, --cmd
- Update tmpfiles comment to reflect actual requirement

This provides a minimal, stable login that works reliably.
User can reboot to test.

+# Project Profile: nixos-config
+
+A reliable, elegant, multi-system NixOS flake configuration for personal desktop, server, cloud, Home Manager, package, overlay, and secret management.
+
+> Last updated: 2026-05-29T16:02:11.092188Z | Version: 1
+
+## Goals
+
+- **reliability** [high]: Keep all managed NixOS systems reproducible, reliable, and easy to validate before deployment. (active)
+- **architecture** [high]: Maintain an elegant multi-system architecture with clear host boundaries and reusable common modules. (active)
+- **modularization** [high]: Continue breaking up the former monorepo by keeping Home Manager profiles in m3ta-home and custom packages/modules in m3ta-nixpkgs where appropriate. (active)
+- **automation** [medium]: CI/CD is not currently configured; add useful Gitea Actions validation later for formatting, linting, flake evaluation, and safe host checks. (deferred)
+
+## Tech Stack
+
+### Languages
+
+- Nix (primary system, module, overlay, and package configuration language)
+- Markdown (project, agent, and workflow documentation)
+- JSON/YAML (tool configuration and metadata)
+
+### Frameworks
+
+- Nix flakes [reproducible dependency and output model]
+- NixOS modules [host and service configuration]
+- Home Manager [user environment management]
+- Agenix [encrypted secret management]
+- Disko [server disk provisioning]
+- NUR [community package access]
+- llm-agents.nix [LLM agent packages overlay]
+- m3ta-home [external reusable Home Manager profiles]
+- m3ta-nixpkgs [external custom packages/modules/overlays]
+
+### Infrastructure
+
+- m3-ares [desktop NixOS host]
+- m3-kratos [desktop NixOS host]
+- m3-daedalus [portable laptop/Home Manager configuration]
+- m3-atlas [primary server NixOS host]
+- m3-helios [minimal server/AdGuard host]
+- m3-hermes [secondary server/Hermes host]
+- m3-aether [cloud VM/minimal server host]
+
+**Build tools:** nix, nixos-rebuild, nix build, nix flake show, alejandra, statix, deadnix
+
+**Package managers:** nix flakes
+
+## Architecture
+
+**Pattern:** Pure Nix flake-based NixOS configuration repository with host-specific modules, common shared modules, overlays, custom packages, agenix secrets, and externalized Home Manager/package inputs.
+**Data flow:** flake.nix wires inputs, overlays, packages, NixOS modules, and Home Manager. Host modules import common configuration and host-specific hardware/programs/services/secrets. Host profile flags in hosts/common/users/m3tam3re.nix feed the external m3ta-home mkHome integration. Secrets flow through agenix registry and host secret modules.
+
+### Modules
+
+| Module | Path | Description |
+|--------|------|-------------|
+| flake.nix | `flake.nix` | Top-level entry point defining inputs, packages, overlays, Home Manager modules, NixOS configurations, and dev shells. |
+| hosts/common | `hosts/common` | Shared NixOS configuration, nix settings, overlays, Home Manager setup, ports, extra services, and users. |
+| hosts | `hosts` | Per-host NixOS/Home Manager configurations for desktops, servers, and cloud VM. |
+| modules/nixos | `modules/nixos` | Reusable NixOS modules. |
+| modules/home-manager | `modules/home-manager` | Reusable Home Manager module exports. |
+| overlays | `overlays` | Nixpkgs overlays for stable, locked, pinned, master, temporary, and agent packages. |
+| pkgs | `pkgs` | Custom package export set. |
+| secrets | `secrets` | Encrypted agenix secret files and registry. |
+
+**Entry points:** `flake.nix`, `hosts/<host>/default.nix`, `hosts/<host>/configuration.nix`, `hosts/common/default.nix`, `hosts/common/users/m3tam3re.nix`, `overlays/default.nix`, `pkgs/default.nix`, `secrets.nix`
+
+## Team
+
+- **m3tam3re** (solo developer and operator): architecture, implementation, host maintenance, deployments, review
+- **m3ta-chiron** (agent contributor): semi-autonomous implementation, validation, documentation updates, conventional commits
+
+## Workflows
+
+### development
+
+Default feature-branch workflow for solo development with conventional commits and validation before push.
+**Triggers:** new feature, bug fix, refactor, agent task
+
+1. review Beads issues with bd ready --json
+2. claim work with bd update <id> --claim when applicable
+3. edit Nix modules or project files
+4. run alejandra .
+5. run statix check .
+6. run targeted nix flake or host dry-run checks
+7. commit with conventional commit format
+8. pull --rebase and push
+
+### nix validation
+
+Quality gate for Nix configuration changes.
+**Triggers:** Nix code changes, before deployment, before commit
+
+1. alejandra .
+2. statix check .
+3. deadnix check or deadnix -w when appropriate
+4. nix flake show
+5. sudo nixos-rebuild dry-run --flake .#<host> for affected hosts
+
+### host deployment
+
+Manual deployment after successful dry-run validation.
+**Triggers:** manual host update
+
+1. sudo nixos-rebuild dry-run --flake .#<host>
+2. sudo nixos-rebuild switch --flake .#<host>
+
+### dependency/input update
+
+Controlled flake input updates without manually editing flake.lock.
+**Triggers:** planned dependency update, security update
+
+1. use nix flake update or nixos-rebuild --update-input <input>
+2. validate affected outputs
+3. commit flake.nix/flake.lock changes
+
+### beads issue tracking
+
+Persistent issue tracking and session handoff workflow.
+**Triggers:** start of tracked work, completion of tracked work
+
+1. bd ready --json

+## Processes
+
+- **Babysitter project install** (`cradle/project-install`, undefined)
+
+## Tools
+
+### Linting
+
+- statix
+- deadnix
+
+### Testing
+
+- nix flake show
+- nixos-rebuild dry-run
+- nix build
+
+### Formatting
+

+
+## Services
+
+- **code.m3ta.dev** (git hosting) - git+ssh://gitea@code.m3ta.dev
+- **GitHub** (flake input hosting) - github:* flake inputs
+- **Agenix** (secret encryption) - github:ryantm/agenix
+- **Hermes Agent** (NixOS module/agent service) - github:NousResearch/hermes-agent
+- **RustFS** (NixOS server service flake) - github:rustfs/rustfs-flake
+
+## CI/CD
+
+**Status:** Not configured/enabled for now.
+
+No Babysitter CI/CD workflow is currently installed. If CI/CD is added later, prefer Gitea Actions because this repository is hosted on code.m3ta.dev.
+
+## Pain Points
+
+- **high** [architecture]: The repository is transitioning away from a monorepo; boundaries with m3ta-home and m3ta-nixpkgs must remain clear.
+  - Remediation: Keep host-specific decisions local while moving reusable Home Manager profiles and package/module abstractions to their dedicated inputs.
+- **medium** [validation]: A single shared Nix change can require validating several hosts to be confident.
+  - Remediation: Use targeted affected-host validation locally for now; add a Gitea Actions validation matrix later if CI/CD is re-enabled.
+- **medium** [dependency management]: Multiple pinned, locked, stable, master, and external SSH flake inputs increase update complexity.
+  - Remediation: Update inputs intentionally, group related updates, and validate affected host outputs.
+- **medium** [operations]: Service additions often need synchronized module, secret, and network/TLS changes.
+  - Remediation: Use checklist-style issue templates or Babysitter processes for service changes.
+
+## Bottlenecks
+
+- flake.nix and flake.lock are high-churn files whose changes can affect many hosts at once. at flake.nix, flake.lock (very frequent)
+  Impact: High; evaluation failures can block all hosts.
+- Secret registry and host secret modules must stay aligned with encrypted .age files. at secrets.nix, hosts/*/secrets.nix, secrets/*.age (recurring)
+  Impact: Medium to high; missing or mismatched secrets break host deployment.
+- Server service changes can span service modules, secrets, Traefik/networking, and flake inputs. at hosts/m3-atlas/services, hosts/m3-hermes/services, hosts/common (frequent)
+  Impact: High for m3-atlas and m3-hermes changes; requires host-specific dry-runs.
+- Home Manager behavior depends on both the external m3ta-home input and local host flags. at flake.nix, hosts/common/users/m3tam3re.nix, m3ta-home input (frequent after migration)
+  Impact: Medium; may require coordinated updates across repositories.
+
+## Conventions
+
+### Naming
+
+- **files:** hyphen-case for Nix/docs where practical; host directories use m3-* names
+- **hosts:** m3-<greek-name>
+- **modules:** one module per file/directory where possible
+- **nixVariables:** camelCase
+
+### Git
+
+- **branchStrategy:** default feature branches for non-trivial work; master as integration branch
+- **commits:** conventional commits for agent work
+- **reviews:** optional for solo development
+- **releaseCadence:** continuous/manual as needed
+- **remote:** code.m3ta.dev over SSH for private inputs and repo access
+
+**Import order:** module function arguments > imports > let bindings > options/config
+
+**Error handling:** Nix configuration should fail explicitly during evaluation/build; avoid hiding errors or impure paths.
+
+**Testing:** Run alejandra, statix, deadnix as appropriate, nix flake show, and host-specific nixos-rebuild dry-run before switching.
+
+### Additional Rules
+
+- Use Beads for persistent task tracking.
+- Use non-interactive flags for shell file operations.
+- Do not modify flake.lock directly; use nix flake update.
+- Do not commit plaintext secrets.
+- Use SSH URLs for code.m3ta.dev flake inputs.
+- Operate Babysitter semi-autonomously with breakpoints for destructive, deployment, or architecture-changing decisions.
+
+## Repositories
+
+- **nixos-config** [`/home/m3tam3re/p/NIX/nixos-config`]
+- **m3ta-home** - git+ssh://gitea@code.m3ta.dev/m3tam3re/m3ta-home
+- **m3ta-nixpkgs** - git+ssh://gitea@code.m3ta.dev/m3tam3re/nixpkgs
+
+## CLAUDE.md Instructions
+
+- Respect AGENTS.md as the source of project workflow rules.
+- Resolve the active Babysitter process library before using library processes.
+- Use cradle/project-install for project setup or profile refresh.
+- Use evolutionary GSD: map affected Nix modules/hosts, make focused changes, verify, and iterate.
+- Prefer alejandra, statix, deadnix, nix flake show, and targeted host dry-runs for Nix changes.
+- Preserve boundaries between nixos-config, m3ta-home, and m3ta-nixpkgs.
+- Use breakpoints for destructive operations, deployments, architecture changes, and secret-handling decisions.
+- Babysitter CI/CD is not currently enabled; if re-added later, use Gitea Actions rather than GitHub Actions.
