"""F4 RED — pins .claude-plugin/plugin.json.version to F4 release.

Fails until plugin.json.version is bumped 0.0.1 -> 0.1.0.

Contract: plugin.json.version is the single source of truth for plugin
version. Git tag mirrors it as 'v' + version. Marketplace
plugins[0].source.ref must equal 'v' + version (covered by
test_marketplace_json_schema.py). Bumping version requires updating this
pin.
