Skills go stale as APIs change and data sources move. This adds a three-layer
staleness detection system: review date tracking with git fallback, HTTP health
checks for declared dependencies, and top-level key comparison for schema drift.
All new frontmatter fields are optional — existing skills work unchanged.

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.

Adds skill_registry.py CLI tool with 7 subcommands (init, publish, list,
search, install, info, remove) for managing a git-friendly shared skill
catalog. No new dependencies — stdlib only. Integrates with existing
validate.py and security_scan.py for publish-time checks.
