Fix labeler.yml for actions/labeler@v5 compatibility

[Copilot]

Summary

Labeler workflow failing with "found unexpected type for label 'documentation' (should be array of config options)". Configuration file format incompatible with actions/labeler@v5.

Changes

• Bug fix
• Feature
• Docs
• Chore / maintenance

Migration to v5 format: Updated .github/labeler.yml from v4 simple glob arrays to v5 structured matchers:

# Before (v4)
documentation:
  - '**/*.md'
  - 'docs/**/*'

# After (v5)
documentation:
  - changed-files:
      - any-glob-to-any-file: ['**/*.md', 'docs/**/*']

All 8 label categories (documentation, workflows, ci, dependencies, scripts, tests, configuration, community) updated. No functional changes to matching logic.
