feat: lessons-learned loop — win signals + skill_edit auto-apply

Adds two new hook signal types:
- correction_free_streak: 5 consecutive UserPromptSubmits without a correction phrase
- clean_recovery: 3 clean PostToolUse events after a struggle signal
  (tool_error_loop / dead_end / retry_loop)

Both carry active_skills/active_agents payloads computed from a 10-event
activity ring, so ADAM can attribute wins to whichever skill was active
during the streak/recovery.

Promotes skill_edit to auto-apply under a strict gate (all required):
- conf >= 4 + cross-session evidence (existing rules)
- # Why cites a win-signal entry whose active_skills includes target
- diff append-only, +lines <= 30
- resulting SKILL.md size <= 2x current size
- 7-day cooldown per target (last_auto_edit in applied/ frontmatter)
- 30-day blacklist on user rejection (auto_apply_blacklist in rejected/)

Skill enforces the gate at apply time as defense in depth: re-stats target,
re-checks cooldown and blacklist, verifies append-only, reverts and refuses
on byte-cap breach. User-rejected skill_edit proposals automatically write
auto_apply_blacklist: true.

Win signals participate in the existing v0.2.0 source_entries archive
lifecycle, so already-applied evidence does not re-cluster.

Test suite: +5 cases (5 new asserts pass), 27 total passing.
