feat: add referenceURL lookup and replace regression tests with Vitest integration suite

Add referenceURL parameter to get_record_by_identifier for x-devonthink-item:// URL
lookup, supporting both UUID and non-UUID formats (e.g. imported emails with
message-ID-based reference URLs). Uses three-tier lookup: UUID fast path,
lookupRecordsWithURL scan, and brute-force referenceURL comparison fallback.

Replace monolithic regression-test.ts with a proper Vitest integration test suite
split by domain (connectivity, CRUD, identification, organization, transformation,
network, AI). Tests use globalSetup/globalTeardown with an isolated temp database,
ensuring no impact on production data. Covers 28 tests across all 27 MCP tools.
