test: add bulk task and epic search tests (+9 tests, 100% coverage)

Add tests for tasks_bulk_move, tasks_bulk_priority, tasks_bulk_delete
including edge cases (non-existent IDs, verify state after bulk ops).
Add epic search tool exercise test. All 4 previously under-covered
tool files now at 100% line coverage.

1818 tests across 45 suites.
