Martin Vogel a1d849aaaa Fix all memory leaks, vendor sqlite3, add Docker test infrastructure ...

Leak fixes (13 sources, 1.4MB → 0 bytes):
- Cypher: free col_names after rb_set_columns, free rejected inline
  prop nodes, store WITH aliases in qualified_name for auto-cleanup
- Store: add cbm_project_free_fields, fix find_node_ids_by_qns leak
- Graph buffer: free strdup'd hash keys during delete operations
- SQL scanner: free old start_tag before reassignment in deserialize

Platform independence:
- Vendor sqlite3 amalgamation (3.49.1) — eliminates system libsqlite3
  dependency, enables full ASan/LeakSanitizer instrumentation
- Add -I for vendored tree-sitter unicode headers — eliminates hidden
  dependency on system libicu-dev
- Add test-infrastructure/ with Docker Compose for local GCC+ASan
  testing that mirrors CI exactly
