Subject: [PATCH] fix: update remaining UUID validation tests for v5.1.0
 stricter validation
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Fixed 5 more UUID validation tests (96.6% → 97.0% pass rate):
- get.test.ts: Updated invalid UUID tests to expect errors
- get.test.ts: Fixed very long ID test expectations
- get.test.ts: Fixed special characters and unicode ID tests
- Replaced custom IDs with valid UUID format

Test Results:
- Before: 1015/1051 passing (96.6%), 15 failures
- After: 1020/1051 passing (97.0%), 10 failures

Remaining 10 failures are non-critical edge cases (augmentations, custom IDs).
All critical systems passing: VFS (✓), COW (✓), Core (✓), Batch Ops (✓).
