agentws manages per-branch git worktrees for the unkin-agent user: it clones
repos into the source root (~/src/prodenv/<repo>) so branches are visible in
Ben's main checkout, and creates isolated worktrees under the worktree root
(~/.cache/agentws/<repo>__<branch>).
- New internal/agent/git.go: small, testable git helpers shelling out to the
git binary (clone/fetch/worktree add/remove/list/prune, branch + config ops,
porcelain parsing, path sanitizing). No go-git dependency.
- New cmd/agentws: new / list / rm / clean / token / credential subcommands.
Auth uses an ephemeral git credential helper (agentws credential get) so the
~1h Gitea token is never persisted in a remote URL or config; per-worktree
config keeps the shared checkout's identity untouched.
- Wire agentws into Makefile, scripts/build-rpm.sh, packaging/nfpm.yaml (binary
+ bash/zsh/fish completions), .woodpecker/release.yaml (cross-compile + assets)
and .gitignore.
- Tests: table tests for parsing/sanitizing/dir-naming, a real temp-git repo for
the worktree lifecycle, and hermetic cmd tests (bad input + credential-helper
host guard) that never touch the network.
- Document agentws in README.md and AGENTS.md.
