- Extend cmdStatePrune to prune Performance Metrics table rows older than cutoff
- Add workflow.auto_prune_state config key (default: false)
- Call cmdStatePrune automatically in cmdPhaseComplete when enabled
- Document workflow.auto_prune_state in planning-config.md reference
- Add silent option to cmdStatePrune for programmatic use without stdout
Closes#2087

Review feedback from @trek-e — address scope gaps:
1. **--dry-run mode** — New flag that computes what would be pruned
without modifying STATE.md. Returns structured output showing
per-section counts so users can verify before committing.
2. **Resolved blocker pruning** — In addition to decisions and
recently-completed entries, now prunes entries in the Blockers
section that are marked resolved (~~strikethrough~~ or [RESOLVED]
prefix) AND reference a phase older than the cutoff. Unresolved
blockers are preserved regardless of age.
3. **Tests** — Added tests/state-prune.test.cjs (4 cases):
- Prunes decisions older than cutoff, keeps recent
- --dry-run reports changes without modifying STATE.md
- Prunes resolved blockers, keeps unresolved regardless of age
- Returns pruned:false when nothing exceeds cutoff
Scope items still deferred (to be filed as follow-up):
- Performance Metrics "By Phase" table row pruning — needs different
regex handling than prose lines
- Auto-prune via workflow.auto_prune_state at phase completion — needs
integration into cmdPhaseComplete
Also: the pre-existing test failure (2918/2919) is
tests/stale-colon-refs.test.cjs:83:3 "No stale /gsd: colon references
(#1748)". Verified failing on main, not introduced by this PR.
