feat(db): decision ID claim system — prevent cross-worktree collisions

- `db/connectors/decision next [D|Q|R]` — show next available ID
- `db/connectors/decision claim <prefix> <domain> [title]` — reserve ID in DB
- `db/connectors/decision check-dupes` — detect duplicate IDs in markdown
- `tooling/check-decision-ids` — pre-commit hook for dupe detection
- D-035 added as known exception (139 files, too embedded to renumber)

### File conventions
- Decisions: domain files in `decisions/` (see `decisions/README.md` for index)
- Decision IDs: `D-NNN` (confirmed), `Q-NNN` (open questions), `R-NNN` (rejected)
- **Claim IDs before writing:** `db/connectors/decision claim D <domain> "title"` — prevents ID collisions across worktrees
- Diagrams: `.d2` source + `.png` renders in `docs/diagrams/{category}/`. Create or update diagrams via `/d2-diagram` when D-records are added or modified.
- Discussion rounds: numbered sequentially, archived to `docs/discussions/` when complete
- Briefings: one per agent, updated after decision-producing rounds

Parses all markdown files in decisions/ (excluding README.md), extracts
decision blocks (D-NNN, Q-NNN, R-NNN), and syncs them into the decisions
and decision_refs tables.
Idempotent: safe to run repeatedly. References are rebuilt on every sync.
ID claiming workflow:
1. Agent calls 'claim D architecture "Per-game save dirs"'
2. Gets back D-085 (or whatever is next)
3. Agent writes D-085 in the appropriate domain file
4. Pre-commit hook runs check-dupes to catch collisions
