feat: expose non-interactive permission status

[Betafer]

Summary

Add a non-interactive permission-status command to the installed Sender and Receiver binaries.

Setup and support tools can now inspect the exact binary that will run without constructing the Sender service, opening a window, starting capture or attaching a virtual display.

Both binaries print the same stable single-line format:

TB_PERMISSION_STATUS:screen_recording=N:accessibility=N:input_monitoring=N

The Receiver reports screen recording as zero because it does not capture the screen; it reports its Accessibility and Input Monitoring trust directly.

Scope

• two production files
• read-only command-line behavior
• no permission prompts or settings changes
• normal app startup is unchanged when the flag is absent

Verification

• rebased onto maint-3.5 at v3.5.1-rc.3
• Receiver: 642 checks pass and full build succeeds
• Sender: all 111 XCTest cases pass
• both built binaries were executed with permission-status and returned the expected parseable line without opening their normal UI
