Adds an opt-in C5-internal orthorectifier (`_orthorectifier.py`) that
emits at most one tile-aligned JPEG candidate per nav frame to the
C6 `TileStore.write_tile` API. Quality gates fire before any
OpenCV work: covariance Frobenius, inlier floor, source-label
(`SATELLITE_ANCHORED` only), and once-per-frame rate limit.
Cross-component import rule (AZ-507) is preserved: c5_state never
imports c6_tile_cache. `runtime_root.state_factory` carries a new
`_C6MidFlightIngestAdapter` that builds the canonical
`TileMetadata` (`ONBOARD_INGEST` / `FRESH` / `PENDING`), hashes
the JPEG, and translates `FreshnessRejectionError` to a `None`
return so the orthorectifier silently swallows freshness
rejection per AC-NEW-3.
Wiring is opt-in via `C5StateConfig.orthorectifier.enabled`;
existing tests/binaries default to disabled and are unaffected.
Both `GtsamIsam2StateEstimator` and `EskfStateEstimator`
participate through new `attach_orthorectifier` /
`set_latest_nav_frame` extension methods (Protocol surface
unchanged).
Tests: 22 new unit tests cover AC-1..AC-9 plus inlier-floor
gate plus the composition-root adapter. 216/216 c5_state and
38/38 runtime-root + compose tests pass.
