feat(camera): third-person rig, V toggle, visible body

One pawn, both rigs (ADR-9): a skeletal body hidden in first person, a
collision-tested spring arm, and a toggle that swaps the active camera and the
body's visibility. Shipped default stays first person; -thirdperson starts the
pawn in the third-person rig so the review shot is reproducible, and the
screenshot run passes it.

Three defects found and two fixed:
- The skin material had no SkeletalMesh usage flag, so Unreal silently substituted
  the default grey. That is why the body rendered as clay.
- render_screenshots.sh still called ./Engine/... on this branch (the fix lives on
  the facade branch and never reached main); applied here so the shots generate.
- OPEN: the idle clip is bound and PlayAnimation is called - the run logs the clip
  name - but the body still renders in bind pose, arms out. Recorded with that
  evidence in TODO.md rather than called done.

Shot 5 (demo-third-person) added and documented; camera collision is implemented
but unproven, since the spawn has open space behind it.

+## ADR-9: Third-person body is an attachment of the first-person pawn, not a second pawn
+
+- **Context**: `0.2.0` needs a visible body and a third-person camera, while `0.1.0` shipped a first-person pawn with no body and the owner's decision was first person for that release. Two separate pawn classes would duplicate movement, input and reset logic, which is the code most likely to drift.
+
+- **Decision**: one pawn, both rigs. `AGigLineCharacter` carries a skeletal mesh (hidden in first person), a collision-tested spring-arm camera, and a **V** toggle that swaps the active camera and the body's visibility. The shipped default view stays first person; `-thirdperson` starts the pawn in the third-person rig and is what the screenshot run passes, so the review shot is reproducible without a human pressing a key.
+
+- **Consequences**: movement, reset, pause and the QA self-test stay in one place. The body's animation state is driven from `Tick` by speed rather than from input, so being pushed or falling animates correctly. The cost is that the camera swap is not a separate actor, so a future cinematic camera needs its own path rather than reusing the toggle.

+## 0.2.0 third-person body — what to look at
+
+Shot 5 is the review for the third-person rig. It is **not** a finished body: the figure is in bind pose, arms out.
+
+What is implemented and visible:
+
+- The pawn carries a visible skeletal body with the warm skin material (the material needed `used_with_skeletal_mesh=True`; without it Unreal silently substituted the default grey, which is what the first render showed).
+- A spring-arm camera with collision testing, and a **V** toggle between first and third person. The shipped default stays first person; the review passes `-thirdperson` so the shot is reproducible.
+
+What is **not** working, with evidence:
+
+- The idle clip is bound and `PlayAnimation` is called — the run logs `GigLine: playing body clip Character_AnimHuman_rig_GigLine_Idle` — but the body still renders in bind pose. The clip therefore is not deforming the mesh; that is the open defect, tracked in `TODO.md` under "Verify animation plays correctly on the imported rig".
+- The arms-down offsets are baked into the clips as a base on top of the A-pose bind (`BASE` in `Tools/character_anim_build.py`), so a correct playback should show arms down. Seeing them out is the same defect, not a missing offset.

 - [x] Create basic idle/walk animation set. Done 2026-11-09: `Tools/character_anim_build.py` authors `GigLine_Idle` (60 f) and `GigLine_Walk` (30 f) at 30 fps from parametric cycles, and `Tools/ue_character_anim_import.py` imports them. Both AnimSequences verified in `/Game/Test/Character`: Idle 1.967 s, Walk 0.967 s. Limb axes were **measured** on the rig, not assumed — the probe rotated `upperleg01.L` 0.5 rad per axis and read `foot.L`, which showed X is the fore/aft swing (Y twists, Z abducts).
-- [A] Verify animation plays correctly on the imported rig. Import-time verification passes (two AnimSequences, correct lengths); **playback on a possessed pawn is not yet verified** — it needs the third-person camera item below, because the demo pawn carries no visible body. Visual confirmation lands with that item.
+- [A] Verify animation plays correctly on the imported rig. **Playback is broken and now measurable**: the pawn's mesh is bound, both clips resolve, and the run logs `GigLine: playing body clip Character_AnimHuman_rig_GigLine_Idle`, but shot 5 still renders the body in bind pose (arms out). So `PlayAnimation` is called and the pose is not applied — next step is to check whether the imported clip carries bone curves at all (the FBX bake may be sampling only keyed bones) or whether the component needs `SetAnimationMode(AnimationSingleNode)` before `SetAnimation`/`Play`.
 
 ### Camera and controls
 
-- [ ] Add third-person camera following the player body.
-- [ ] Add first/third-person toggle.
-- [ ] Add camera collision to prevent clipping through geometry.
+- [x] Add third-person camera following the player body. Done 2026-11-09: `USpringArmComponent` + camera on the capsule, boom 340 cm, lag 8, and the body is the animated skeletal mesh with the skin material. Review shot 5 (`demo-third-person`, `Screenshots/README.md`) shows the rig; the shipped default view stays first person.
+- [x] Add first/third-person toggle. **V**, via `IA_ToggleCamera`; the toggle swaps the active camera and the body's visibility. `-thirdperson` on the command line starts in third person so the review is reproducible.
+- [x] Add camera collision to prevent clipping through geometry. The spring arm's collision test (`bDoCollisionTest`, probe 12 cm on `ECC_Camera`) shortens the boom instead of letting the camera pass through a wall. **Not yet exercised against a wall in a shot** — the spawn point has open space behind it, so this is implemented but unproven.
