fix(ci): update both puppeteer install steps with working-directory

Issue:
- Previous fix only updated compatibility matrix job
- Main test job still using old puppeteer command
- Both jobs need puppeteer run from CLI directory

Changes:
- Test job: Add working-directory: ./cli
- Compatibility job: Already fixed with working-directory
- Both now use: npx --yes puppeteer browsers install chrome

Why:
- Puppeteer is CLI dependency (via omniscript-converters)
- Must run from CLI directory to find puppeteer in node_modules
- --yes flag bypasses interactive prompt in CI

Testing:
- All local checks passing
- Lint: ✓ Format: ✓ TypeScript: ✓ Tests: ✓ 130/130
