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.

- **Vertical slice done (session 0012):** the Right-variant half is
productionized and run for the **forest** scale — `simulator/bake_right_variants.py`
(the POC flow-restyle algorithm, repo-resident) bakes real strengths 1–4 on a
by-eye keyframe-strength ramp; forest now carries real Right variants in the
sim, so the dreamlike-axis look is judgeable on real footage. **Still
deferred:** real Right variants for cosmos/abyss (need their real strict-PD
bases sourced first) and the **real i2v ring transitions** (need a 2nd real
base + a generative-video model not in the POC). Plan:
[`2026-06-08-v2v-vertical-slice-forest-right-variants.md`](./superpowers/plans/2026-06-08-v2v-vertical-slice-forest-right-variants.md).
