On Windows, static imports in register-shortcuts.ts (added in v2.72) can
fail at module load time, causing the entire GSD extension to silently fail
to register. This makes /gsd unavailable despite the welcome screen
suggesting it.
Three changes:
- index.ts: register /gsd command before importing register-extension.js,
wrapped in try-catch so bootstrap failures don't prevent core command
- register-extension.ts: remove duplicate registerGSDCommand call, wrap
non-critical registrations (tools, shortcuts, hooks) in individual
try-catch blocks so one failure doesn't prevent others
- Add structural contract tests verifying isolation properties
