feat(sim): forest carries real multi-strength Right variants

Browse Source 
Ran the baker for the forest scale: real flow-stabilized painterly Right variants
1-4 now back the dreamlike axis on real Yosemite footage (was: 1 real + 3 ffmpeg
placeholders). By-eye finding this surfaced: sd-turbo's painterly transform is
sharply non-linear in img2img strength (barely registers <0.5, ramps hard through
~0.5-0.65), so the initial linear 0.28-0.58 ramp left levels 1-3 ~identical to
raw. Re-baked with a clustered 0.46/0.52/0.58/0.64 curve -> a real perceptual
ramp: gentle dream haze -> clearly impressionist -> strongest, each notch visibly
dreamier, temporally calm (flow-stabilized).

- manifest: forest right_variants 1-4 all model 'sd-turbo+farneback-flow'
- setup_sample_media.py: now only stages the neutral base; the baker owns the
  Right variants, so re-running it never clobbers a real bake
- docs: USER_GUIDE setup steps + ROADMAP v2v vertical-slice-done note

Suite 228 passed / 2 skipped.

**One-time setup — populate the sample footage** (look-tuning only; not shipped

`setup_sample_media.py` copies the session-0008 POC artifacts (`~/hef-poc/out/`)
into `simulator/sample_media/forest/` — the neutral base clip and the real
flow-stabilized Right restyle — and generates placeholder intermediate Right
strengths. `setup_scales_media.py` makes the scale **ring** demonstrable: cheap
synthetic placeholder bases for the two true-PD scales (`cosmos` = NASA/Hubble,
`abyss` = NOAA Ocean Exploration) plus the per-edge zoom/warp transition clips.
The `.mp4` binaries are gitignored.
`setup_sample_media.py` stages the forest neutral base from the session-0008 POC
artifacts (`~/hef-poc/out/neutral.mp4`). `bake_right_variants.py` then produces
the **real** flow-stabilized painterly Right variants (strengths 1–4) for the
forest scale — SD img2img keyframes + Farneback optical-flow tweens on Apple MPS,
the temporally-calm POC algorithm, productionized (scales design §1/§4). The
keyframe-strength ramp per Right level is by-eye tunable in
`simulator/bake_right_variants.py`. `setup_scales_media.py` makes the scale
**ring** demonstrable: cheap synthetic placeholder bases for the two true-PD
scales (`cosmos` = NASA/Hubble, `abyss` = NOAA Ocean Exploration) plus the
per-edge zoom/warp transition clips — these scales carry a raw base only (no real
Right variants yet; the baker can extend to them once their real footage is
sourced). The `.mp4` binaries are gitignored.
