## Why
Version sync across all plugin manifest locations so the CC plugin loader,
the .github marketplace mirror, and the canonical plugin.json files all
report the same version.
## Impact
Consumers fetching the plugin via the marketplace will see the updated
version entry.
Skills and evals migrated from .agents/ to plugins/bin/ plugin directory.
Remove .mcp.json, provider-manifest.sh, and skills-lock.json legacy artifacts.
