Adds tools/analyze_265_steep_slope_capture.py (segment miner for the
ACDREAM_CAPTURE_RESOLVE JSONL captures: uphill-jump-bounce and
lost-slide/edge-wedge signature scans) and
tests/AcDream.Core.Tests/Physics/Issue265SteepSlopeCaptureBisectTests.cs (a
synthetic single-polygon PhysicsEngine that replays the EXACT real captured
ballistic approach + landing from artifacts/matrix-session2-resolve.jsonl
records 3415-3434, driving PhysicsEngine.ResolveWithTransition directly at
the Core boundary).
Mining found two dramatic real "velocity annihilation + permanent freeze"
events (records 3153/3159 and 3433/3434): a high-speed fall lands on a
moderate roof slope (normal.Z=0.857, ABOVE PhysicsGlobals.FloorZ — walkable
by threshold), and the very next tick shows Velocity forced to exactly
(0,0,0) with the position frozen byte-identical for the rest of the capture
(12,292 ticks to EOF for the second event).
No production code changes. Full Core.Tests suite: 4070 passed / 2 skipped.
