test(library-desk): add comprehensive entity linking tests
Add test suite covering: - Entity mention detection (case-insensitive, whole-word matching, sorting) - Content link addition (protection of existing links, longest-first matching) - Integration tests (get entities with paths, create relationships, idempotency) - Multi-tenancy isolation tests All 17 tests passing. Validates entity linking functionality end-to-end. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

Comprehensive tests for Entity Linking system.
|
||||
|
||||
Tests cover:
|
||||
- Finding entity mentions in pages
|
||||
- Creating MENTIONS relationships in Neo4j
|
||||
- Adding hyperlinks to wiki content
|
||||
- Idempotency (safe to run multiple times)
|
||||
- Protection of existing links (no nesting)
|
||||
- Multi-tenancy isolation
|
||||
|
||||
Run with: pytest tests/test_entity_linking.py -v -s
