a4948d9545 fix(hnsw): resolve segfault with parameterized queries (Issue #141) 
This commit fixes a critical P0 bug where HNSW indexes on ruvector
columns would crash PostgreSQL with a segmentation fault when using
parameterized queries (prepared statements, ORMs, application drivers).

Root Cause:
- Query vector extraction failed for parameterized queries
- Code fell back to zero vector without validation
- Zero vector caused segfault during HNSW search

Changes:
- Add multi-method query vector extraction pipeline
  1. Direct RuVector::from_polymorphic_datum()
  2. Text parameter conversion for parameterized queries
  3. Validated varlena fallback with dimension checking
- Add query_valid flag to track extraction success
- Add validation before search execution:
  - Reject empty/invalid query vectors with clear errors
  - Reject all-zero vectors (invalid for similarity search)
  - Validate dimension match between query and index
- Apply same fixes to IVFFlat for consistency

Testing:
- Added regression tests for parameterized queries
- Added tests for zero vector error handling
- Added tests for dimension mismatch errors
- Added 384-dimension production-scale tests

Fixes: #141
See: docs/adr/ADR-0027-hnsw-parameterized-query-fix.md

43b2c1a1c0 fix(postgres): remove broken integration test files 
The standalone test files in tests/ directory were causing linker errors
when running cargo pgrx test. These tests referenced non-existent functions
and tried to link against pgrx symbols without PostgreSQL libraries.

The actual pg_test tests are in src/operators.rs and other source modules.

- FILTER expressions with 50+ built-in functions
- Standard result formats (JSON, XML, CSV, TSV, N-Triples, Turtle)

PostgreSQL Functions:
- ruvector_sparql() - Execute SPARQL queries with format selection
- ruvector_sparql_json() - Execute queries returning JSONB
