The context cancel in pruneRepoWorktrees was called explicitly after
CombinedOutput inside a loop. Extract to a helper method so defer
cancel() works correctly (scoped to the function, not the loop).

- Move WriteGCMeta from runTask() to handleTask() so it runs after
task completion, not at start. Mid-task crashes leave orphan dirs
that get cleaned by GCOrphanTTL.
- Strengthen isBareRepo to check both HEAD and objects/ directory.
- Remove empty workspace directories after all task dirs are cleaned.
- Add 30s context timeout to git worktree prune to prevent hangs.
- Add comprehensive unit tests for shouldCleanTaskDir (8 scenarios),
cleanTaskDir, gcWorkspace empty-dir cleanup, isBareRepo, and
WriteGCMeta/ReadGCMeta roundtrip.

Isolation directories accumulate indefinitely because they're preserved
for session reuse but never cleaned up after the issue is closed.
This adds a background GC loop that periodically scans local workspace
directories and removes those whose issue is done/canceled and hasn't
been updated for 5 days (configurable via MULTICA_GC_TTL). Orphan
directories with no metadata are cleaned after 30 days.
Changes:
- Write .gc_meta.json (issue_id, workspace_id) at task completion
- Add GET /api/daemon/issues/{issueId}/gc-check endpoint for status queries
- Add gcLoop goroutine to daemon with configurable interval/TTL
- Prune stale git worktree references from bare repo caches each cycle
- New env vars: MULTICA_GC_ENABLED, MULTICA_GC_INTERVAL, MULTICA_GC_TTL,
MULTICA_GC_ORPHAN_TTL
