[e4ed92d6] Video pipeline per-project requests, re-render action, composition preview (#403)

* [7f2c881a] Project-scope video pipeline + re-render + preview proxy (#386) (#396)

* [7f2c881a] feat(video): scope on-demand video requests + render loop to project_id

Require project_id on VideoRequestBody (404 when unresolvable or not
opted into the video engine), thread it through VideoEngine.open_video_task
via a shared resolve_authoring_project helper, and resolve the render
loop's motion/ workspace from the authoring task's own project_id instead
of the hardcoded self_heal_project_slug.

* [7f2c881a] fix(video): cast task.id to UUID before VideoEngine.rerender calls

mypy flagged task.id as sqlalchemy.sql.sqltypes.UUID[Any] rather than
uuid.UUID in the three rerender tests; cast to UUID per the codebase's
established idiom (cast("UUID", obj.id)) used elsewhere for the same
SQLAlchemy Mapped-attribute inference gap.

* [7f2c881a] docs(video): API endpoints for project-scoped requests, re-render, and preview proxy

Add comprehensive API documentation for the new project-scoped video engine endpoints:
- POST /api/video/request: on-demand video authoring scoped to project_id (breaking change)
- POST /api/video/pipeline/{task_id}/rerender: CEO-triggered re-render with idempotency key clearing
- GET /api/video/preview/{task_id}/{file_path}: CEO preview proxy with path-traversal confinement

Document project-scoping architecture: authoring tasks and render loop now resolve from task's own project_id instead of hardcoded self_heal_project_slug.

Add migration guide covering breaking change to VideoRequestBody schema (project_id now required), error handling changes (404 on unresolvable/non-opted-in projects), and client migration steps.

* [03607ab9] Fix re-render control gating/placement and project picker filter (#434)

* [f2f3e89f] Fix RerenderControl gating/placement across queue and strip views (#431)

* [f2f3e89f] feat(video): widen RerenderControl gating and share it across queue/strip views

Extracts RerenderControl into a shared panel/src/components/dashboard/
video-rerender-control.tsx component, widens its gate from
render_status === 'failed' to source_task_id + composition_id present
(matching what the backend rerender endpoint actually requires), adds a
confirm dialog before firing the mutation, and wires the same component
into video-pipeline-strip.tsx for still-in-flight rendering/render_failed
rows.

* [f2f3e89f] docs(video): enhance RerenderControl JSDoc with gating logic and usage examples

Add comprehensive JSDoc to the RerenderControl component covering its
purpose, gating logic (render for any source_task_id + composition_id,
regardless of render_status), three visual button states (idle/loading/
error), confirm-dialog guard behavior, and usage examples for both
video-post-queue.tsx and video-pipeline-strip.tsx contexts. Explains
why the backend's rerender endpoint doesn't require a failed render and
how the component prevents accidental re-renders.

* [404d8ed3] Filter project picker to video-engine-enabled projects (#432)

* [404d8ed3] feat(panel): filter video-request project picker to opted-in projects

Add video_engine_enabled to the client ProjectSummary type, give
ProjectSelector a videoEngineOnly filter prop, default RequestVideoDialog's
picker to the current video-enabled project with a friendly empty-state
when none exist, and cover the filter with a new project-selector test.

* [404d8ed3] docs(panel): add ProjectSelector component API reference with videoEngineOnly filter

Document the reusable ProjectSelector component with its props, filtering behavior,
and new videoEngineOnly filter for video-engine-enabled projects. Follows the
existing component documentation pattern from page-refresh-provider.

* [9c7bc11a] docs(standards): document markdown reflow quality gate workflow and verification

Added comprehensive guide explaining the one-logical-unit-per-line markdown prose standard, how the reflow check integrates into make quality, the three reflowed files (video-engine-endpoints.md, video-project-scoping.md, composition-controls spec), and the regression test added to ensure wiring stability. This task verifies all three ACs are satisfied: reflow_md.py --check exits 0, make quality passes (non-DB portions), and the three files are whitespace-only reflowed.

* [e4ed92d6] fix rerender missing-task test — assert the empty queue it creates

The test never seeds; the trailing assertion expected a phantom video
post. Broken since the branch's first commit but never executed — every
earlier CI run short-circuited at a pre-pytest gate step.
