feat: initial m3ta-home structure

- flake.nix with nixpkgs, home-manager, nix-colors, m3ta-nixpkgs, agenix, NUR inputs - lib/mkHome.nix: compose HM config from user + identity + context + sets - profiles/base: shell, cli-tools, secrets (always loaded) - profiles/contexts/desktop: WM, apps, theme, ghostty - profiles/contexts/server: minimal headless - profiles/sets/coding: core (git, direnv, jq, rg), editor, lsp, languages, agents - profiles/sets/gaming: steam, gamescope, gpu - profiles/sets/media: obs, ffmpeg, kdenlive, handbrake, yt-dlp - users/m3tam3re/identities: private.nix, work.nix (git, jj, ssh per identity) - users/m3tam3re/preferences: cliphist, difftastic, base packages
