fix: correct plugin schema and improve descriptions

Schema Fixes:
- Fix plugin.json: author must be object (not string)
- Remove unsupported fields: tags, compatibility
- Fix marketplace.json: update owner to darrenhinde
- Remove tags from plugin entry (not supported in schema)

Description Improvements (reviewed by CodeReviewer):
- Marketplace: Focus on workflow automation benefits
- Plugin: Emphasize shipping faster with AI-powered workflows
- Highlight context-aware agents and cross-IDE compatibility
- Use outcome-oriented language vs technical jargon

Changes:
- plugin.json: author string → object, removed tags/compatibility
- marketplace.json: improved descriptions, updated owner
- All schema validation errors resolved

Fixes Claude Code validation errors:
- 'author: expected object, received string'
- 'Unrecognized keys: tags, compatibility'
