Adds s_churn/s_tmin/s_tmax to sample_funpack_distilled_flow: optionally
re-noise the latent within [s_tmin, s_tmax] before each eval, then denoise
from the bumped sigma_hat. No extra model calls (still one eval per step,
at a higher noise level). Fights stale/frozen distilled output (more motion)
and can sharpen by letting the model re-resolve. sigma_hat is clamped to the
schedule start so the model never sees a higher-than-trained noise level, the
final jump-to-zero detail step is never churned, and the default 0.5-1.0 band
protects the sub-0.4 detail finish per the empirical sigma findings.
Churn supersedes the legacy s_noise ancestral path while active and is
video-stream-only on packed LTXAV latents. With s_churn=0 the sampler is
byte-identical to the previous deterministic ODE. Wired into the node and
Studio's Distilled Flow config panel.

Port the Hybrid/RF velocity-bias capture/apply and rating-gated reactive
rescue into sample_funpack_distilled_flow, reusing the shared trajectory
memory helpers. Adds velocity_bias_mode/strength/source/key and
rescue_mode/threshold/strength to the FunPackDistilledFlowSampler node and
wires them into Studio's Distilled Flow config panel (same blank/'default'
velocity-key -> refinement-key fallback as Hybrid). Steering is
magnitude-preserving and, on packed LTXAV latents, video-stream only
(audio-safe). With all controls off the sampler is byte-identical to the
previous deterministic ODE.

Document the three undocumented releases (2.7.5 embed guidance + online
value function + mid_scene_guide; 2.7.6 value-function ascent + rating
overhaul; 2.7.7 reactive rescue + Batch Training) and bring the Scene
Chain Sampler, Hybrid Euler-2S, and Studio docs in line with current
parameters and features.

Add confirmed-bad-combo warnings to both parameter tooltips, the sampler
doc, and the changelog. Warn users not to combine frame_overlap=0 with
carry_i2v_guides=True in normal use.

Perfect is not a ceiling. If the user has an active advisor mode and
provides feedback_prompt, the advisor must honor it regardless of the
rating. Two guards were blocking this:
- Analysis pass (pass 1): was skipped when is_perfect=True even with no
feedback, so Full/Only-diagnostics mode produced no analysis for
Perfect runs. Removed the not-is_perfect restriction so analysis runs
whenever mode requires it and no explicit feedback was given.
- Repair guard (pass 2): had an explicit is_perfect-and-not-has_feedback
branch that silently blocked repair for every Perfect run with no user
text. Removed it entirely. The only remaining guard is the existing
allow_prompt_change check (Learning mode / advisor mode Off).
Now for Perfect + user feedback: advisor honors the feedback fully.
For Perfect + no feedback + Full mode: analysis runs, repair runs.

- CHANGELOG: add new Changed and Fixed entries for negative conditioning
removal, advisor system prompt rewrite, token limit increases, Only
prompt double-call fix, and encoded_prompts bug fix.
- README: update 2.5.0 section to cover all of the above.
- docs/FunPackVideoRefinerV2.md: remove negative_prompt input and
modified_negative output; update advisor_mode description with new
structured input format and token budgets; update encoded_prompts
output description with all four possible sections.
