[AZ-696] chore: cycle-2 bootstrap — gitignore tlog inputs, Step 9 PBIs

Pre-implement chore commit to land orchestration artifacts produced by
autodev cycle-2 Step 9 (New Task), so that Step 10 (Implement) starts
against a clean working tree.

What's included:

- .gitignore: exclude _docs/00_problem/input_data/**/*.{tlog,mp4,h264}
  (derkachi.tlog is a 5.8 MB binary input and stays out-of-band).
- _docs/02_tasks/todo/AZ-697..AZ-702: 6 new PBI specs under epic AZ-696
  (tlog ground-truth extractor, mid-flight trim+align, real-flight
  validation runner, replay map viz, HTTP replay API, KHP20S30 calib).
- _docs/02_tasks/_dependencies_table.md: dep edges for the 6 PBIs.
- _docs/_autodev_state.md: status -> in_progress, step 10 cycle 2.
- _docs/_process_leftovers/...opencv_pin_deferred.md: replay-attempt
  timestamp refreshed (gtsam-numpy-2 wheels still not published;
  leftover remains open).

No source code is modified by this commit.

 # D-CROSS-CVE-1 opencv-python pin deferred — gtsam/numpy ABI block
 
 **Recorded**: 2026-05-11T02:55+03:00 (Europe/Kyiv)
-**Last replay attempt**: 2026-05-19T20:04+03:00 (Europe/Kyiv) — replay re-checked
-at start of next `/autodev` invocation (~55 minutes after prior check at 19:09).
-PyPI not re-queried this round (debounced — `gtsam` upstream state is highly
-unlikely to publish numpy-2 wheels within a <2-hour window of the prior check,
-and the previous check confirmed no movement). Replay condition (numpy>=2
-stable wheels) still NOT met. Leftover remains open.
