FT-P-12: parse mavproxy-listener tlog over a 60 s Derkachi replay and
assert SUT->GCS GLOBAL_POSITION_INT cadence lands in [1, 2] Hz (AC-6.1).
FT-P-13: inject `RELOC:<lat>,<lon>,<radius_m>` STATUSTEXT while the SUT
is in dead_reckoned; verify FDR `c8.gcs.operator_command` ack <=2s,
`anchor_search_region` centre shifts toward the hint, and no
BAD_SIGNATURE / UNAUTHORIZED / REJECTED STATUSTEXT lands in the
post-inject window (AC-6.2).
Adds runner.helpers.gcs_telemetry_evaluator (rate, hint-ack correlation,
haversine search-region shift, rejection scan) and
sitl_observer.capture_gcs_tlog (parity surface to capture_ap_tlog).
Pure-logic coverage: 39 new unit tests; full e2e/_unit_tests/ suite
746 passing (was 700). Scenarios skip locally on missing SITL replay
fixture; production hooks (inbound STATUSTEXT parser, anchor_search_region
FDR emitter) tracked outside this task.
