docs: update README and obsidian docs with reservation improvements

Document self-blocking prevention (excludeUserID), explicit reservation cancellation endpoint, background cleanup goroutine, and edit_request reservation scrubbing. Bump test counts from 1,169 to 1,180 and package count from 19 to 20. Add race detector command to README.

 ## Features
 
-**Booking**: Self-service (customer), walk-in (admin), call-in (admin). Slot reservations prevent double-booking (4 TTL types). Guest accounts with GDPR-compliant anonymization. Service eligibility based on age + patch test validity. Overlap checks use `FOR UPDATE` row locks inside transactions. Closing-hours validation extracted into a reusable `closing_time` helper.
+**Booking**: Self-service (customer), walk-in (admin), call-in (admin). Slot reservations prevent double-booking (4 TTL types). **Self-blocking prevention**: `excludeUserID` parameter filters a user's own `RESERVATION` entries from time blocker overlap checks, allowing re-reservation and booking at overlapping slots. **Explicit cancellation**: `DELETE /api/bookings/reserve` releases a user's reservation. **Background cleanup**: 5-minute goroutine clears expired reservations. Guest accounts with GDPR-compliant anonymization (including `RESERVATION:edit_request:%` scrubbing). Service eligibility based on age + patch test validity. Overlap checks use `FOR UPDATE` row locks inside transactions. Closing-hours validation extracted into a reusable `closing_time` helper.
 
 **Payments**: Square Terminal (in-person) + Web Payments SDK (online). Cash with change calculation. Gift cards (12-digit code or account balance). Saved cards for faster checkout. Tips on completed bookings. Refunds with notice-period tiers and deposit protection (72h/24h thresholds). All payment types: deposit, full, partial, balance, tip. Payment >20% of total promotes `pending_release` bookings back to `confirmed`. Deposit paid is computed from payments on-the-fly. The first 50% of each payment is always carved out as deposit (via `buildSplitRecords`); any overflow beyond the booking total becomes a tip. A PostgreSQL `pg_advisory_lock` serializes payment attempts per-booking to prevent two-tab double-payment races. Gift card purchases now insert a pending payment record with VAT before calling Square — the DB transaction commits first, so Square failures leave a retryable pending record.
