review: restore character + cubes in ReviewMap, re-render all shots

Root cause of the empty review frames: EditorLevelLibrary.load_level/new_level
are deprecated no-ops in -nullrhi commandlets, so staged actors landed in the
current world and got saved over the wrong map. Switched both map builders to
the LevelEditorSubsystem and reordered the review builder to save ReviewMap
before the DemoMap section (the switch-back to a map that only exists in
memory silently failed, writing demo content over ReviewMap).

Rebuilt both maps, re-rendered every screenshot; user visual check passed.
Screenshots/README.md cube naming corrected (A grounded, B floating), approval
states updated; TODO.md visual-review notes closed. MEMORY.md records the
deprecated-call and save-order traps.

 - [x] Give the MPFB character asset a standing idle pose so review and NPC shots show a person, not an A-pose bind. Done: `Tools/mpfb_character_export.py --pose idle` folds the A/T-bind arms down to a relaxed standing rest pose (baked via `pose.armature_apply` before export; `upperarm01.L` rest z −0.71 → −1.91 rad), re-exported, re-imported (138 bones), rendered in `review-01-character`.
 - [x] Bake a second skin tone or clothing layer, so the character does not read as a grey mannequin in shots. Done: the v2-skin bake came out **black** and slow at 1024², so we synthesize a warm skin-tone diffuse directly (`Tools/mpfb_character_export.py` `make_diffuse`, with a darker shorts-suggestive bottom band) via a stdlib/numpy PNG writer. Character reads warm, not grey. Screenshot approved (`Screenshots/review-01-character`).
-- [x] Keep the character as a reusable NPC prefab: a visible body, a collision capsule, and a head-height check that the camera does not clip at 1.60 m — for when NPCs/pedestrians are wired in (`0.2.0+`), not the `0.1.0` player. Done 2026-11-07: `AGigLineNPCPerson` (C++), ACharacter with capsule half-height 83 cm / total 1.66 m (head at ~1.66 m, so a 1.60 m camera does not clip), the MPFB human on the built-in mesh as the visible body, `AutoPossessAI` for pedestrians; confirmed spawned feet-on-Z-0 and rendered in `Screenshots/review-npc-prefab` (☐ pending approval).

 - [x] First-person movement, mouse look, and Enhanced Input bindings. Implemented 2026-11-07: `AGigLineCharacter` (C++, 1.75 m capsule, 1.60 m eye camera, 4 m/s walk, mouse look in deg/s, jump) as the default pawn, with five actions and an 11-entry context in `/Game/Input` built by `Tools/ue_create_input_assets.py`. **Not yet confirmed interactively** — launch PIE on `Test/ReviewMap` and walk. Screenshot review pending (`Screenshots/README.md`).
 - [~] Collision, reset, and pause functionality. Reset (**R**) and pause (**Escape**, a real game pause that releases the cursor) are implemented in `AGigLineCharacter` with `/Game/Input/IA_Reset` and `IA_Pause`. Collision now exists — terrain, road and sidewalks import as complex-as-simple, so a simple hull cannot ramp over the kerbs. **Not verified by hand**: walk, reset and pause need a human at the keyboard. No pause menu widget yet, only the pause itself.
-- [-] Build the walkable demo level: terrain, street, and hero facade assembled into one map with a start point on the north sidewalk, so the demo is something a player can walk rather than a review staging. **Built 2026-11-07** by `Tools/ue_build_demo_map.py` → `/Game/Hollywood/DemoMap`: sun/sky, `Hero_Facade`, six site meshes imported with collision (`Terrain_DEM`, `Road_Hollywood`, both sidewalks and both kerbs), and a `Demo_PlayerStart` on the north sidewalk 20 m back from the frontage. Demo views in `Screenshots/demo/` are ☐ pending review.
-- [x] Walkable sidewalks and a designated street crossing. Crossing chosen: mid-block signalised crossing, OSM way 385648319, at 130 m along the block (`Geo/verification/2026-11-06-street-profile.md`). Done 2026-11-07: continental zebra markings (0.5 m bars / 0.5 m gaps, 3 m band) at all three signalised crossings, no collision on the paint; kerbs were already flushed at the crossings. Enablers found on the way: the street surfaces were 100 % down-facing (invisible in engine) — winding flipped; the terrain buried the street — 10.7 m corridor cut around the centreline (sidewalks cover the transition, walk-check 0 holes); LFS-lockable `.blend`/`.umap` check out read-only — builders now chmod before saving and fail loudly. Screenshot review pending (`Screenshots/demo/review-demo-crossing`); the corridor renders near-black in shadow — that is the still-open **Fixed daytime lighting** item, not the crossing.
