Resolve task_capability_map.py conflict by keeping all three capability
entries: commit_files and gitea_commit_files (gitea.repo.commit, #262,
from master) and reconcile_merged_cleanups (gitea.read, #269, this
branch). Capability boundaries unchanged — reconciliation reporting stays
read-only; no close/merge capability broadened.

Implement gitea_reconcile_merged_cleanups with dry-run reporting for merged
PR remote branches and local branches/ worktrees, plus confirmation-gated
execute mode. Safety gates cover protected branches, open PR references,
active issue locks, dirty worktrees, and delete_branch capability.
Closes#269
