Migrate commands to skills across all plugins

- Convert all commands/*.md files to skills/*/SKILL.md format
- Merge 36 reference-skill pairs into their invokable counterparts
- Mark reference-only skills as user-invocable: false
- Expand descriptions for migrated skills with usage scenarios
- Keep partner-built/ commands as-is
- Remove bio-research from marketplace.json
