- Add platform-specific daemon_unix.go and daemon_windows.go for Setpgid handling (Unix-only syscall) - Fix gofmt issues in watch/watch.go and mcp/main.go 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
When a new directory is created after the daemon starts, the daemon now adds it to the watcher so files created inside are tracked. Fixes: directory CREATE events were filtered out by isSourceFile check 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
Break up the ~680 line watch.go into four single-responsibility files: - types.go: Event, FileState, DepContext, Graph, State structs - daemon.go: Daemon struct and lifecycle (NewDaemon, Start, Stop) - events.go: event loop, handling, logging, and delta calculations - state.go: PID management, state persistence, daemon control No functional changes - all tests pass. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

Summary
This PR adds a comprehensive Claude Code integration through hooks and a background watch daemon:
Claude Code Hooks (
cmd/hooks.go,HOOKS.md) - Automatic context injection at every step of a Claude Code session:session-start: Shows project structure and hub filespre-edit/post-edit: Warns when editing high-impact filesprompt-submit: Detects file mentions and shows dependency contextpre-compact: Saves hub state before context compactionsession-stop: Summarizes session changes and stops daemonWatch Daemon (
watch/watch.go) - Background file watcher that tracks:.codemap/state.jsonFileGraph (
scanner/filegraph.go) - Import/dependency analysis:MCP Server enhancements - New tools for live watching and file context
Tests - Added
