chore: add PHPDoc to Priority 1 Enterprise classes

Added @since, @param, @see tags to:
- CliFramework: class-level @since, 2 undocumented methods
- GitHubAdapter: class @since/@see, constructor @param, property docs
- MokoGiteaAdapter: class @since/@see, constructor @param, property docs
- ApiClient: class @since

Wiki: created Coding-Standards page with full PHPDoc standard,
PHPCS exclusion rationale, and file structure patterns.

Partial progress on #137
