test: add coverage for sidebar-agent, file-drop, and watch mode
33 new tests covering: - Sidebar agent queue parsing (valid/malformed/empty JSONL) - writeToInbox file drop (directory creation, atomic writes, JSON format) - Inbox command (display, sorting, --clear, malformed file handling) - Watch mode state machine (start/stop cycles, snapshots, duration) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
