v0.1.16

feat: smart dev server restart for component overrides

- Scan dashboard source at startup to build knownDashboardComponents set
- Track appliedOverrides dynamically during esbuild pre-bundling
- File watcher only restarts Vite when override files change:
  - ADD: restart if name matches a known dashboard component
  - CHANGE: restart only if it's an active override
  - UNLINK: restart only if it was an active override
- No hardcoded lists — everything is scanned dynamically

Bump to 0.1.16
