fix(ci): use npx --yes for puppeteer chrome installation

Issue:
- Puppeteer Chrome installation failing in CI
- 'pnpm add -D puppeteer' tries to modify frozen lockfile
- Exit code 127 - command not found or failed

Solution:
- Remove 'pnpm add -D puppeteer' step
- Use 'npx --yes puppeteer browsers install chrome' directly
- Puppeteer is already in dependencies via omniscript-converters
- --yes flag bypasses npx prompt in CI environment

Why This Works:
- Puppeteer package installed via pnpm install
- Just need to download Chrome browser binary
- npx can access puppeteer from node_modules

Testing:
- Lint check: ✓ passed
- Format check: ✓ passed
- Type check: ✓ passed
- Tests: ✓ 130/130 passed locally
