Fix remaining test failures and schema mismatches

- Update fuzzy matching functions to return relative paths
- Fix findDocument to properly separate displayPath and filepath
- Update MCP test schema to use content-addressable storage
- Remove deprecated getCollectionIdByName function references
- Fix MCP collection filtering to work post-search
- Update test expectations for YAML-based collections
- Fix integration test expectations for path formats

Test results: 244 passing / 16 failing (93.8% pass rate)
