fix(ci): resolve turbo recursive build loop and filter issues

**Problem:**
- CI build was failing with "Cannot find module manifest-full.js"
- Root cause: Infinite recursive turbo build loop
- chat/package.json had "build": "turbo run build" script
- When CI called `pnpm run build --filter=chat...`, it triggered recursion:
  - CI → turbo → chat:build → turbo → chat:build → turbo (infinite)
- Additionally, `--filter=manacore...` failed with "No package found"

**Solution:**
1. Removed "build" script from apps/chat/package.json to prevent recursion
2. Changed CI filters from `--filter=PROJECT...` to `--filter='./apps/PROJECT/**'`
   - Directory-based filters work regardless of package.json name
   - Prevents recursive turbo calls from wrapper packages
3. Applied fix to all CI jobs: build, lint, type-check, test

**Impact:**
- SvelteKit builds now complete successfully
- manifest-full.js is generated correctly
- No more infinite turbo loops
- Builds work for both chat and manacore projects
