release: v0.2.0 — third-person body, animation, stride capture

Writes the 0.2.0 changelog entry with the measured numbers, removes the completed
section from TODO.md (its goal stays in ROADMAP.md) and updates the roadmap status.

Release checks: 8/8 shots verify with 6, 7 and 8 approved; 1440p at 2.64 ms average
(379 fps); -qaselftest passes walk, reset, pause, transect, wall and facade probes;
82 tool tests pass. Known limitations are listed rather than hidden: splayed fingers,
a swept base rotation and unproven camera collision, all marked for later patches.

+## [0.2.0] — 2026-11-09
+
+Third-person body. The pawn gains a visible, animated body and a third-person camera, so the walk cycle is finally something a player can see rather than a clip in an asset list.
+
+### Added
+
+- **`Tools/character_anim_build.py`**: `GigLine_Idle` (60 frames) and `GigLine_Walk` (30 frames) at 30 fps, authored as parametric cycles so the loop closes by construction. Limb axes were **measured** on the rig — a probe rotated `upperleg01.L` by 0.5 rad on each axis and read `foot.L`, which showed X swings the limb fore/aft while Y twists and Z abducts.
+- **Third-person rig** (`ADR-9`): a visible skeletal body, a `USpringArmComponent` with collision testing, and a **V** toggle. One pawn carries both rigs; first person stays the shipped default.
+- **Walk capture harness**: a per-shot `ShotFollow` mode that re-places the review camera every frame in the pawn's frame, plus `SetReviewWalk` / `ReturnToStartForReview`, so a stride is captured deterministically and the fixed-camera shots still find the pawn at spawn.
+- **Review shots 6, 7 and 8** — third-person back, front and mid-stride — embedded in `Screenshots/README.md`.
+
+### Changed
+
+- Character export preset now **bakes animation** (`bake_anim`, all actions). Without it the exporter wrote a static bind pose and Unreal imported a mesh with no clips and no error.
+- `Docs/controls.md` documents the V toggle and the review switches; the in-game HUD line reads `WASD move · Mouse look · Space jump · V view · R reset · Esc pause`.
+
+### Fixed
+
+- **`PlayAnimation` on a hidden component never took effect.** The body is hidden at construction and only unhidden by the toggle, so the first call could land before the component was ready; the code now sets `AnimationSingleNode`, calls `SetAnimation` + `Play`, and re-asserts while the instance is missing.
+- **The animation switch restarted the clip every frame**, freezing the body on frame 0.
+- **The importer silently refused to replace the existing assets.** Changing the arm rotation and rebuilding returned the identical bone quaternion every time; `replace_existing` and `delete_asset` both failed because the pawn's constructor hard-references the clips. Importing under a new name (`CharacterV2`) finally landed the change — that is what unblocked the pose after a dozen failed rebuilds.
+- **The review runner copied stale screenshots** from `Saved/`, so a shot retired from the camera list reappeared with byte-identical content from an older run. The folder is cleared before each capture.
+- **Walking was never enabled for the stride shot**: the call sat in the shot sequencer's `BeginPlay`, which runs before the player pawn exists, so the cast silently found nothing and `speed` stayed at 0.
+
+### Verified
+
+- **8 review shots verify**; shots 6, 7 and 8 approved by the owner.
+- **1440p, no frame generation, VSync off**: 759 frames, avg **2.64 ms (379 fps)**, p50 2.54, p95 3.39, p99 3.76, max 4.05 ms — about 2 % over `0.1.5` and 6.3× the 60 fps floor. Series: `Docs/perf/0.2.0-walk-frametimes.csv`.
+- `-qaselftest`: walk, reset 0 cm from spawn, pause/unpause, transect 1456 samples / 0 holes, wall probe 0/35, façade probe 0/9 — all PASS.
+- 82 tool tests pass.
+
+### Known limitations
+
+- **The fingers splay** — the bind's finger spread carries into the pose. Deferred to `0.2.2`.
+- **The arms-down rotation was found by sweeping**, not derived: 0.55 rad puts the arms at the sides, 0.65 against the hip, 0.75 into the torso. A derived pose is a `0.2.2` job.
+- **Camera collision is implemented but unproven** — the spawn point has open space behind it, so no shot exercises the boom shortening.
+- The third-person body has no head or hand IK and no turn-in-place; it is a first playable, not a finished character.

 Retail frontage. The two retail buildings beside the hero are modelled from their own photograph instead of the generic kit, and the photograph is treated as evidence: an analysis is written before any geometry, and every dimension the image does not resolve is carried into the part report as an assumption.
