 Notes:
-  - For git installs: fetches, rebases, installs deps, builds, and runs doctor
+  - Switch channels with --channel stable|beta|dev
   - For global installs: auto-updates via detected package manager when possible (see docs/install/updating.md)
   - Downgrades require confirmation (can break configuration)
   - Skips update if the working directory has uncommitted changes
