### 22A. Session-owned worktree cleanup and TTL (#401)
Every session-owned worktree created under `branches/` has ownership metadata:
path, workflow type, issue number, PR number, branch/head SHA, creator
identity/profile, created timestamp, last-used timestamp, and cleanup
eligibility.
Cleanup is classification-driven. `gitea_audit_worktree_cleanup` (read-only)
classifies every `branches/` entry as exactly one of:
* `active_open_pr` — branch has an open PR; never auto-removed.
* `active_issue_work` — active claim/lease or fresh issue worktree; never
auto-removed.
* `dirty_local_worktree` — uncommitted changes; never auto-removed.
* `clean_stale_removable` — clean, no PR, no lease; removable.
* `detached_review_leftover` — clean detached review/baseline/merge-simulation
worktree; removable.
* `unsafe_unknown` — protected base checkout or unknown workflow type; never
auto-removed.
Only `clean_stale_removable` and `detached_review_leftover` may be removed, and
only one-by-one after `git worktree list` proof plus per-worktree proof of:
worktree path, branch/HEAD, clean/dirty status, no active PR/lease, and the
removal result. Review, baseline, and merge-simulation worktrees are removed
automatically at successful workflow completion; issue/conflict-fix worktrees
are removed only after their TTL (`GITEA_WORKTREE_TTL_HOURS`, default 24h)
expires and no lock/lease is held.
Dirty, active-PR, active-issue, and leased worktrees are never deleted
automatically. If a removal fails, the final report must list the leftover
worktree path and the reason. Include the `git worktree list` output as final
cleanup verification.
