feat(pipeline): render queue, worker service and automated preview generation
One "Queue Export" click now renders the EXR sequence, then rebuilds the shot headlessly with the studio slate/overlay template to produce the delivery MOV and review MP4. Implements RenderPipeline2 phases 1-2 plus the preview stage. Server: - New models Export, RenderJob, ExportEvent, Machine, WorkerHeartbeat, plus Project.deliveryConfig and per-submission slate fields (Export.vfxScope, Export.submissionNote, inherited from the shot's previous export). Both migrations are purely additive; no existing column is touched. - lib/render-pipeline: server-enforced state machine, transactional version increment with supersede, atomic FOR UPDATE SKIP LOCKED claim gated by machine availability windows, and a lease reaper run from instrumentation.ts. - /api/ext/* endpoints for the panel and workers; session-auth mirrors under /api/render and /api/machines for the web UI. - Pipeline pages: render queue, export detail, machine monitoring, plus an Exports tab on shot detail. RenderWorker (.NET 8 Windows service, new): - Registration, heartbeat as cancel channel, claim loop, aerender runner with progress parsing and stall watchdog, crash recovery and disk-spooled reporting that survives server downtime. - Preview stage: headless AE assembles the preview comp into a throwaway AEP with both output modules queued, then a single aerender pass renders them. Preview jobs are not claimed while an interactive AE session is open, so an artist's project is never taken over. AE panel: Queue Export with live status polling, urgent flag, retry, and the VFX Scope / Submission Note fields. Every existing panel action is unchanged. Preview chaining ships disabled behind SystemConfig preview.enabled. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

.SYNOPSIS
|
||||
Headless AE spike / debug tool for the preview build stage.
|
||||
|
||||
.DESCRIPTION
|
||||
Runs vfxr_build_preview.jsx exactly the way the RenderWorker does, but
|
||||
standalone, so the risky part (AfterFX.com -noui -r under a service
|
||||
account) can be proven before wiring the whole pipeline together.
|
||||
|
||||
It does NOT render - it builds the preview comp, queues the MOV + MP4
|
||||
output modules and saves a temp AEP, then prints the build result.
|
||||
|
||||
IMPORTANT: close After Effects first. `AfterFX.com -r` hands the script to
|
||||
an already-running instance, which would open the template in your session
|
||||
and then quit it.
|
||||
|
||||
.EXAMPLE
|
||||
.\test-preview-build.ps1 -ExrDir "V:\_EXPORTS\UNG\renders\UNG_S1\111\UNG_111_001_030\v002" `
|
||||
-ShotCode "UNG_111_001_030" -Version "v002"
|
||||
|
||||
.EXAMPLE
|
||||
# then render what it built, exactly as the worker would:
|
||||
& "C:\Program Files\Adobe\Adobe After Effects 2026\Support Files\aerender.exe" -project "$env:ProgramData\VFXReviewWorker\scratch\spike_preview.aep"
