Fix codex call

Codex client never returns a cut stream as an answer (0.10.2) (#56)

The subscription backend only streams. A stream that closed before
response.completed returned its partial text, so callers parsed empty or
truncated JSON (a breakdown's location step failed on both). Such a
stream is now retried twice and then raised; response.incomplete reports
its reason; the completed response's output text is preferred over the
joined deltas.

Update breakdown

Preserve screenplay boundaries and quoted breakdown evidence (#55)

* Keep screenplay boundaries and source evidence through breakdown

* Pin source-grounded scene skills for default breakdown installs

Actions and emotions name the character who performs them

Actions and emotions name the character who performs them (0.10.0) (#54)

* Actions and emotions name the character who performs them (0.10.0)

Action and Emotion gain character_id, as Dialogue already has speaker: an
action beat in a multi-character shot could not say whose it is, so
consumers had to guess from the description's wording. Optional and
recommended; None when no listed character performs the beat. Registered in
the field tiers, the field registry and the events pillar schema; the spec
appendix is regenerated (276 -> 278 fields).

* Lock the 0.10.0 version

Modify greybox concept to 3D modeling

Rename the greybox concept to 3D modeling (0.9.0) (#52)

The panel scene is built by the 3D modeling stage now, so the code, docs and
tests say so: panel_greybox -> panel_modeling, greybox_gate -> modeling_gate,
make_panel_greybox -> make_panel_modeling, Paths.greyboxes_dir -> modeling_dir,
PanelGreyboxSpec -> PanelModelingSpec, and the Blender kernel 'greybox' ->
'modeling'. Prose says "3D model". The on-disk layout is unchanged.

Convert scene to USD/FBX

Keep cameras when converting scenes to GLB, and read USD (0.8.1) (#51)

The convert kernel exported GLB with the glTF exporter's defaults, which
leave cameras out, so an animated camera in an uploaded FBX never reached
camera extraction. Export cameras, and import .usd/.usda/.usdc/.usdz with
Blender's USD importer. A Blender-gated test converts an FBX and a USD
with an animated camera and checks the GLB carries it.
