What the worker reported about the change:
- **Conflict:** it was confined to the two version lines in `plugins/omni/.claude-plugin/plugin.json` and `.claude-plugin/marketplace.json`. I took main's `0.4.304` in both.
- **Version bump:** `python3 scripts/validate_plugin.py --base origin/main --bump-to-base` raised both to `0.4.305`. `python3 scripts/validate_plugin.py --base origin/main` then exited 0, and the commit hooks passed, including `validate-plugin`.
Facts the worker recorded for the commit body:
Version conflict in plugin.json and marketplace.json resolved to main's 0.4.304, then bumped to 0.4.305 with validate_plugin.py --bump-to-base.
