feat: implement independent package versioning

[devin-ai-integration]

Changes

• Bumped @lit-protocol/uint8arrays version to 8.0.0 for testing individual package versioning
• Added version-check.spec.ts test to verify version changes

Test Strategy

1. Manual verification:

   • Confirmed uint8arrays version is 8.0.0 in dist/packages/uint8arrays/package.json
   • Verified other package versions remain unchanged (e.g., @lit-protocol/constants and @lit-protocol/types still at 7.0.4)

2. Automated testing:

   • Added version-check.spec.ts test that verifies:
     • uint8arrays version is 8.0.0
     • Dependencies maintain their original versions

Build Verification

• Successfully built uint8arrays package with new version
• Dist output correctly reflects version change
• Other package builds unaffected by version change
