scripts/termux-preflight.py runs the docs/termux-operator.md §0.1-0.5 checks on
the phone and prints a PASS/FAIL report: python>=3.11, requests/rich/websockets
import, cryptography+Fernet round-trip (version floor treated as soft), srp
C-ext OR the pure shim, that client/operator import without the server stack,
and an AF_UNIX bind under the $TMPDIR runtime root. Makes the one remaining
on-device Phase-0 step a single command. Exits non-zero on any hard failure.
