feat: add detailed error logging to keyword sync workflow

API Changes:
- Return errorMessages array in sync response (first 5 errors)

Workflow Changes:
- Display error messages in GitHub Actions logs with formatting
- Include error details in Discord notifications (first 3 errors)
- Shows errors in both console output and Discord embed

Example output:
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
⚠️  SYNC ERRORS (4 total):
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
  • Failed to process pkg1: Invalid tpmjs field
  • Failed to process pkg2: Network timeout
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
