- Critical Issue: Filter node_modules and target directories in code search. The filter_entry closure now checks skip_dirs for ALL directories, not just those starting with '.'. This ensures node_modules and target are properly skipped. Added unit test code_search_skips_node_modules_and_target to verify. - Important Issue: Collapse nested if-let chains in orchestrator.rs using Rust 2024 let-chains. The try_unblock_tasks method now uses a single if let ... && let ... condition instead of nested blocks, resolving the clippy collapsible_if warning. - Minor Issue: Tighten assertion in code_search_skips_binary_files test. Removed the vacuous disjunction - the '.' regex always matches text.txt, so the assertion now directly checks for "text.txt" presence. Verification: - All 7 code_search unit tests pass - Full test suite passes (all 100+ tests) - cargo clippy clean (collapsible_if warning resolved) - cargo build successful Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
