All other search DTOs (SemanticSearchBodyDto, HybridSearchBodyDto,
BrainQueryDto, BrainSearchDto) already enforce @MaxLength(500) on their
query fields. SearchQueryDto.q was missed, leaving the full-text
knowledge search endpoint accepting arbitrarily long queries.
Adds @MaxLength(500) decorator and validation test coverage.

Replace inline type annotations with proper class-validator DTOs for the
semantic and hybrid search endpoints. Adds SemanticSearchBodyDto,
HybridSearchBodyDto (query: @IsString @MaxLength(500), status:
@IsOptional @IsEnum(EntryStatus)), and SemanticSearchQueryDto (page/limit
with @IsInt @Min/@Max validation). Includes 22 new tests covering DTO
validation edge cases and controller integration.

Implemented three new API endpoints for knowledge graph visualization:
1. GET /api/knowledge/graph - Full knowledge graph
- Returns all entries and links with optional filtering
- Supports filtering by tags, status, and node count limit
- Includes orphan detection (entries with no links)
2. GET /api/knowledge/graph/stats - Graph statistics
- Total entries and links counts
- Orphan entries detection
- Average links per entry
- Top 10 most connected entries
- Tag distribution across entries
3. GET /api/knowledge/graph/:slug - Entry-centered subgraph
- Returns graph centered on specific entry
- Supports depth parameter (1-5) for traversal distance
- Includes all connected nodes up to specified depth
New Files:
- apps/api/src/knowledge/graph.controller.ts
- apps/api/src/knowledge/graph.controller.spec.ts
Modified Files:
- apps/api/src/knowledge/dto/graph-query.dto.ts (added GraphFilterDto)
- apps/api/src/knowledge/entities/graph.entity.ts (extended with new types)
- apps/api/src/knowledge/services/graph.service.ts (added new methods)
- apps/api/src/knowledge/services/graph.service.spec.ts (added tests)
- apps/api/src/knowledge/knowledge.module.ts (registered controller)
- apps/api/src/knowledge/dto/index.ts (exported new DTOs)
- docs/scratchpads/71-graph-data-api.md (implementation notes)
Test Coverage: 21 tests (all passing)
- 14 service tests including orphan detection, filtering, statistics
- 7 controller tests for all three endpoints
Follows TDD principles with tests written before implementation.
All code quality gates passed (lint, typecheck, tests).

Add support for filtering search results by tags in the main search endpoint.
Changes:
- Add tags parameter to SearchQueryDto (comma-separated tag slugs)
- Implement tag filtering in SearchService.search() method
- Update SQL query to join with knowledge_entry_tags when tags provided
- Entries must have ALL specified tags (AND logic)
- Add tests for tag filtering (2 controller tests, 2 service tests)
- Update endpoint documentation
- Fix non-null assertion linting error
The search endpoint now supports:
- Full-text search with ranking (ts_rank)
- Snippet generation with highlighting (ts_headline)
- Status filtering
- Tag filtering (new)
- Pagination
Example: GET /api/knowledge/search?q=api&tags=documentation,tutorial
All tests pass (25 total), type checking passes, linting passes.
Fixes#66
