Subject: [PATCH] fix: Prevent Vite file watcher from crashing in Kubernetes

Fixed the crash loop issue caused by Vite trying to watch too many
files (including node_modules) in Kubernetes environment.

Problem:
- Vite dev server was starting successfully
- But then container would crash with "too many open files"
- This caused infinite restart loop (CrashLoopBackOff)
- Error: "failed to create fsnotify watcher: too many open files"

Root Cause:
- Vite's file watcher was monitoring ALL files including node_modules
- In Kubernetes, this exceeded inotify limits
- Each restart would hit the same limit

Solution:
- Added 'ignored' patterns to vite.config.ts server.watch
- Excluded: node_modules, dist, .git, coverage, .cache
- Vite will only watch actual source files in src/
- Dramatically reduces number of watched files

Changes:
- frontend/vite.config.ts: Added server.watch.ignored array

Benefits:
- Container stays running without crashes
- Faster hot reload (fewer files to watch)
- Lower resource usage
- Dev server remains stable in Kubernetes

Testing:
- Tilt will auto-rebuild container with new config
- Container should start and stay running
- Vite dev server will be accessible
- Hot reload will still work for src/ files
