v0.54.0

Fixed — seedance-2.5 takes reference clips; the clip ceiling is per model

The gateway turned on reference video/audio for seedance-2.5 on 2026-09-26
(enterprise#297): its registry entry now carries supportsReferenceMedia: true
and "reference video/audio clips up to 30s each (billed per reference
second)". blockrun_video still refused reference_videos /
reference_audios on 2.5 by name. It now forwards them, with the same limits
as the 2.0 family: 1-3 clips of each type, audio only beside a reference image
or video, never with frame seeds, up to 30 reference images.

The reserve priced every clip at a flat 15.2s. The provider's ceiling is per
model, and the gateway quotes each clip at its model's ceiling
(REFERENCE_CEILING_SECONDS): 15.2s on seedance-2.0 / 2.0-fast / 2.0-mini,
30.2s on 2.5. A 2.5 clip would have reserved half its price on the one rail
where the reserve is the only budget control. One reference video now puts a
5s 720p 2.5 render at ~$11.07 (~7x its ~$1.58 plain price). 1.5-pro still
takes no clips, and the estimator now throws instead of borrowing another
model's ceiling for it.

Rail rules are unchanged: both wallet gateways (blockrun.ai,
sol.blockrun.ai) still refuse every reference field with a 400 before
quoting, so reference media stays account-rail only, 2.5 included.

Added — price rows for the new chat models

blockrun_chat now prices gpt-6-sol, gpt-6-luna, gpt-5.1, claude-opus-5.5,
claude-sonnet-5.5, grok-4.6 and grok-4.7 from the live /v1/models (#163). On
the native Anthropic path the row is the ledger, so opus/sonnet-5.5 previously
booked nothing. gpt-5.6-sol is repriced from $5/$30 to $4/$20 per million
tokens (cut 2026-08-21).

Fixed — huge prompts reserve at the long-context price

Past a model's pricing.long_context threshold the gateway reprices the whole
request, but the chat estimate reserved at base rates, so a huge prompt
under-reserved (gpt-6-astra over 272K tokens reserved $10/$50 against a $20/$75
quote). The estimate and the account ledger now use the highest long-context
step the prompt reaches, copied from the live /v1/models (#165).
verify:prices fails when a live step would settle above the reserve.

Fixed — retired tencent/hy3 dropped from the cheap tier

Hy3 retired on 2026-09-24 and the gateway redirects it to qwen3.7-flash, which
is already in the cheap chain (#164).
