v0.9.0

A smaller range than 0.8.0: the LoRA catalog grows to cover three more
bases, the cost planner is corrected for list-driven and for_each steps,
and export_job reports its zip's real auth gating. No upgrade-order
changes.

LoRA catalog (docs/LORAS.md)

• 11 LTX-2.5 entries added: IC-LoRAs for alpha generation, clean plate,
  colorization, day-to-night, layout-to-render, detail refinement,
  restoration, SDR-to-HDR and water simulation, plus cinemagraph and
  slow-motion control.
• MiniMax-H3 goes to 13 trial and 3 rejected entries beyond the 0.8.0 set:
  styles, speech, orbits, action and motion, and a diffusers-native 4-step
  turbo. FastVideo FastH3 (.diff keys), RAVEN (unrecognised prefix, loads
  nothing silently) and TaoMate (lowercase lora_a/lora_b) are rejected.
• New bases: Qwen-Image-2.1 (10 trial, including three few-step distills
  that need their scheduler and sigma overrides, plus edit LoRAs; Fun-Acc
  rejected) and Z-Image-Turbo (13 trial). The Z-Image entries match
  Tongyi-MAI/Z-Image-Turbo only; whether they apply to the SDNQ
  checkpoint is untested.
• Every new entry pins the repo's current sha, and its header was read
  against the installed diffusers converter.

Cost planning

• other_device figures are re-priced for for_each counts and shifted
  list drivers (#589, #590).
• A shifted per-entry field in a list driver resets to unknown, and a
  summed child figure takes the children's basis (#593). A numeric string
  in a list-driver entry compares as its number (#593).
• Measured MPS cost entries for templates/ltx2/text-to-video and Music 3
  (#590).

Fixes

• assemble-and-score threads sample_rate into its edit join, and mixed-rate
  shots resampled to a pinned sample_rate no longer draw a warning advising
  you to pass it (#594).
• export_job reports the zip's real gating: /exports/*.zip is ungated
  like /outputs, so auth_required is false whether or not the server has
  a token. The MCP next text and the skills now say to fetch open_url and
  unpack into exports/ to bring a project home (#595, #592).

Plugin

• The ltx-2.5, minimax-h3 and minimax-music3 skills moved
  request-specific detail (the LTX caption spec, H3 checkpoint and LoRA
  combinations and cuts recipes, Music 3 loudness) into references/
  beside each SKILL.md, which are read when the skill points there. The
  12 KiB cap applies to SKILL.md alone; a new test fails on an unlinked
  reference or a dead link.
• The H3 and LTX skills point at list_loras.
