- Add missing hook handlers: Stop, SubagentStop, PreCompact
- Replace all string type casting with proper JSON unmarshaling
- Change ToolUseRequest.Parameters from map[string]interface{} to json.RawMessage
- Update helper methods to use json.Unmarshal directly to typed structs
- Replace speech notifications with simple logging notifications
- Update documentation to reflect all hook events and remove speech references
- Add comprehensive CLAUDE.md with architecture overview and development guidance
All hooks now use type-safe JSON handling without .(string) assertions.
Complete coverage of Claude Code events: PreToolUse, PostToolUse,
UserPromptSubmit, Notification, Stop, SubagentStop, PreCompact.
