Fixes
- Missing start.mjs fix: Old versions (pre-0.9.x) used
start.sh. When old upgrade code copies newplugin.json(which referencesstart.mjs) but doesn't copystart.mjsitself, MCP fails. Thepretooluse.mjshook now creates a minimalstart.mjsshim automatically. - Complete self-healing: Hook now handles: copying files to old installPath, updating registry version, nuking stale cache dirs, AND creating missing
start.mjs.
