[AZ-835] Epic split (C1/C2) + workspace-boundary rule expansion

AZ-835 Epic (E2E real-flight validation pipeline, ~17 SP across
6 children C1-C6) supersedes AZ-777 Phase 3+ (bbox-based static
seed). Children C3-C6 deliberately not yet filed — will be
re-estimated after C1+C2 land from real RouteSpec shape and
Route API client ergonomics.

- AZ-836 (C1, 3 SP): TlogRouteExtractor — pure function over
  .tlog binary returning RouteSpec (waypoints + suggested
  region size). Deps: AZ-697 (load_tlog_ground_truth, done),
  AZ-279 (WGS converter, done).
- AZ-838 (C2, 3 SP): SatelliteProviderRouteClient + seed_route.py
  CLI mirror of seed_region.py. Hard-depends on AZ-836's
  RouteSpec dataclass.
- _dependencies_table.md updated with the three new rows.

Workspace-boundary rule expansion: codifies the sibling-repo
task-spec exception (the only permitted write into a sibling
repo) and the "External Systems Are Black Boxes" rule
(contract-only consumption of producer repos like
satellite-provider).

Bookkeeping: _autodev_state.md condensed to <30 lines per the
state.md conciseness rule; opencv-pin leftover replay
re-checked 2026-05-22 (gtsam still only 4.2, replay condition
unchanged).
