Problem

The tmpfiles rule created a .gitconfig at /home/hermes/.gitconfig, but the hermes-agent service sets HOME=/var/lib/hermes, so git never reads it. The file also contained only the literal Nix store path instead of the actual config content (wrong tmpfiles type f instead of L+).

Changes

Remove the dead .gitconfig tmpfiles rule (was at /home/hermes/, never read)
Add GIT_INIT_DEFAULT_BRANCH = "master" to the environment section
Add comment explaining the single-source-of-truth approach

Why env vars > .gitconfig

All git identity is now set via a single mechanism:

GIT_AUTHOR_NAME/EMAIL — author identity
GIT_COMMITTER_NAME/EMAIL — committer identity
GIT_INIT_DEFAULT_BRANCH — default branch (Git 2.28+)

These are injected by the hermes gateway into .env and take precedence over any gitconfig file. No duplication, no tmpfiles rules for git.

refactor: remove redundant .gitconfig tmpfiles rule, use GIT_INIT_DEFAULT_BRANCH env var 1a17b852a1

The .gitconfig at /home/hermes/.gitconfig was never read because the
hermes-agent service sets HOME=/var/lib/hermes. Git identity was already
fully covered by GIT_AUTHOR_* and GIT_COMMITTER_* env vars via .env.

Replace the dead .gitconfig's init.defaultBranch with the env var
GIT_INIT_DEFAULT_BRANCH (supported since Git 2.28).
