test: close macOS platform command-coverage gaps from #1426

[thymikee]

Part of #1426.

The macOS platform manifest records these commands as known gaps because HEAD has no command-specific macOS evidence that meets the manifest contract:

• doctor
• shutdown
• events
• replay
• test
• batch
• diff
• react-native
• trace
• find
• fill
• longpress
• type
• focus
• swipe

Follow-up work should add or identify executable macOS command evidence before changing the manifest rows. Keep the existing macOS replay and provider scenario scope unchanged unless a separate platform-evidence decision explicitly expands it.
