Skills now require -skill suffix for org-wide discoverability (teams
search *-skill to find all skills). Suites use -suite suffix.
Post-creation sharing flow: agent detects gh/glab CLI, creates repo,
adds agent-skill topic, gives shareable one-liner for Slack/Teams.
Supports GitHub, GitLab, Enterprise, and self-hosted instances.
Updated validate.py to warn on missing -skill suffix and error on
deprecated -cskill suffix. Updated architecture-guide.md naming
section to match.
