fix(plugins): sync plugin.json versions with marketplace.json

Plugin load failures were caused by version mismatch between
marketplace.json and individual plugin.json files:
- contract-validator: 1.2.0 vs 1.1.0
- git-flow: 1.2.0 vs 1.0.0
- projman: 3.4.0 vs 3.3.0
- clarity-assist: 1.2.0 vs 1.0.0
- doc-guardian: 1.1.0 vs 1.0.0

Claude Code silently fails to load plugins when versions don't match.
