  1. feat(cypher): add configurable executor modes (nornic/antlr/hybrid) 

    - Add NORNICDB_EXECUTOR_MODE env var (default: hybrid)
- nornic: Fast string-based parser (original)
- antlr: Full ANTLR AST-based parser (for LLM features)
- hybrid: Fast execution + background AST building (best of both)

New files:
- pkg/config/executor_mode.go: Config for executor mode
- pkg/cypher/executor_factory.go: Factory to create executors
- pkg/cypher/hybrid_executor.go: Hybrid executor implementation
- pkg/cypher/executor_interface.go: CypherExecutor interface + ABExecutor
- pkg/cypher/antlr/*.go: ANTLR grammar and parser files

Test coverage:
- executor_factory_test.go: Factory tests
- executor_mode_test.go: Comprehensive mode comparison tests
- hybrid_executor_test.go: Hybrid-specific tests
- ab_test.go: A/B performance comparison tests

Performance (M3 Max):
- nornic: ~422 ns/op
- hybrid: ~433 ns/op (~3% overhead)
- All modes pass identical query tests
