Subject: [PATCH] ci(quality): block on the SIG unit ratchet and commit the SIG
 score floor

Sets hydra-gates-sig-blocking, so gate 122 fails a change that adds or worsens a unit over the SIG 4-star bounds. Adds .github/sig-floor.json, generated by check_sig_floor.py write from development 1c3dff98: the 4-star checks this app meets now, which gate 123 keeps met on every change.
