Greptile Summary

This PR introduces granular node type classification across all language parsers, replacing generic class/interface mappings with language-native kinds (struct, enum, trait, record, module). Both native Rust and WASM extractors updated consistently for Go, Rust, Java, C#, PHP, and Ruby. All SQL query filters across cycles.js, export.js, mcp.js, and watcher.js extended to include the new node kinds.

Key changes:

• Native Rust extractors (6 files) and WASM JS extractors (parser.js) updated to use granular kinds
• Query layer comprehensively updated with new kind IN filters across all modules
• All parser tests updated with new expectations (296 tests passing)
• PreToolUse hooks added for Read/Grep context enrichment via codegraph deps
• Documentation updated: README comparison table includes GitNexus, --kind flag docs updated, CLAUDE.md documents design decision, ROADMAP adds Phase 2.5

Issue found:

• kindIcon() function in queries.js missing cases for new kinds (struct, enum, trait, record, module) — they will display as - instead of meaningful icons

Confidence Score: 4/5

• Safe to merge with one minor display issue in kindIcon()
• Comprehensive implementation with consistent changes across native/WASM extractors and all query layers. Tests pass (296/296). The missing kindIcon() cases is a minor display issue that doesn't affect functionality — new node kinds will render with default - icon instead of specific ones. All breaking changes properly documented.
• Pay attention to src/queries.js — missing icon mappings for new node kinds
