Key changes:
- Add `go get -d golang.org/x/mobile/cmd/gomobile` step (official recommended)
- This adds golang.org/x/mobile dependency to go.mod, fixing "unable to import bind" error
- Remove complex Go 1.22 version detection logic (no longer needed)
- Simplify gomobile installation flow
- Update tsslib/go.mod with proper golang.org/x/mobile dependency
The fix follows the official Go Mobile documentation:
