Extract schema DDL into scripts/schema.sql shared between CLI and app.
Add an in-process chokidar-based indexer-service that watches ~/.claude/projects
for JSONL changes, debounces, and triggers background rebuilds via a worker
thread. Rename Usage view to Activity, flesh out MemoryDetail and SubagentDetail
views, and refine App.vue layout/routing. The main process now starts/stops the
indexer lifecycle and notifies renderer windows on index updates.
