[feat] Add CI checks for OSS license compliance and telemetry tree-shaking

Implements automated verification to ensure the OSS distribution:
1. Only includes open-source licensed dependencies
2. Properly tree-shakes proprietary fonts (ABCROM)
3. Removes telemetry code (Mixpanel) from OSS builds

New scripts:
- scripts/verify-licenses.js - Validates production dependency licenses
- scripts/verify-oss-build.js - Checks dist/ for violations

New CI workflow:
- .github/workflows/ci-oss-compliance.yaml - Runs compliance checks

New npm scripts:
- pnpm verify:licenses - Check dependency licenses
- pnpm verify:oss - Verify OSS build compliance
- pnpm verify:compliance - Run all checks
- pnpm build:oss - Build OSS distribution

Documentation:
- docs/OSS_COMPLIANCE.md - Complete guide for compliance checks
