Oleksandr Bezdieniezhnykh 0d65ff4705 [AZ-339] C2 MegaLoc + MixVPR secondary VPR backbones ...

Adds two research-only VprStrategy implementations for the IT-12
comparative-study matrix. MegaLocStrategy (D=2048, 322x322) and
MixVprStrategy (D=4096, 320x320), both via C7 TensorRT FP16 with
their own concrete BackbonePreprocessor. Single-stage global L2
normalisation; retrieval delegated to FaissBridge; FDR records +
structured logs identical to UltraVPR. BUILD_VPR_MEGALOC and
BUILD_VPR_MIXVPR ON for research/replay-cli only, OFF for airborne
and operator-tooling (fail-fast at composition root via existing
AZ-336 factory). Uses helpers.iso_ts_from_clock from day 1 — no
new timestamp helper duplicates introduced.

36 parametrised AC tests + 25 protocol-conformance + 18 helper
regression tests pass; 1690 / 1690 unit tests pass (excluding 1
pre-existing flaky cold-start subprocess test in c12). Verdict:
PASS_WITH_WARNINGS — one Medium follow-on (AZ-527 to consolidate
4-way _assert_engine_output_dim) + one Low AC wording drift.
