- getDelay indexed by attempt (1-based) into a 0-indexed array, so the
leading 0 was unreachable and every "after a crash" delay was shifted
up one slot. Use attempt - 1 so the documented schedule (0s → 0s →
10s → 30s → 2min → 5min → 15min cap) actually holds.
- enforceStartupBackoff runs before initDb (which creates DATA_DIR), so
on a fresh checkout fs.writeFileSync hit ENOENT. write() now
mkdirSync's DATA_DIR first.
- shutdown() didn't run resetCircuitBreaker if teardownChannelAdapters
threw, so a graceful exit with a teardown error would be counted as a
crash on the next start. Wrap teardown in try/finally.
- Adds src/circuit-breaker.test.ts: state transitions, full schedule
(parameterized), reset-window expiry, malformed file, and the
fresh-install path.

Backs off on rapid restarts to avoid exhausting Discord gateway identify
limits and triggering Cloudflare IP bans. Resets on clean shutdown so only
crashes accumulate the counter. Also adds a troubleshooting section to
CLAUDE.md with the most useful diagnostic locations.
