Honor Num Lock during Remote keyboard capture

Forward numeric keypad identities with Num Lock enabled and preserve held-key pairing across lock changes. Suppress local lock feedback during remote capture so it cannot interrupt incoming speech. Add debug speech and capture-end diagnostics, expand private keypad checks, and repair the suspension probe source list.

Validated affected Go packages, focused remote speech race checks, the private X11 Remote input harness, and a reader build. Live physical keyboard, audible PowerShell speech, Braille, and disconnect-cause verification remain pending; the active reader session was left running.
