# Change: Replace FunClip clip center with VideoAgent workbench

## Why
The current FunClip-based clip center has not completed a reliable editing loop, and its clipping model is too narrow for a commercial AI video production workflow. TrueGrowth needs the clip center to start from user intent and source media, then produce plans, transcripts, segments, packaged outputs, and publishing assets through a broader VideoAgent-style runtime.

## What Changes
- **BREAKING**: Move the customer-facing AI clip workbench primary provider from `funclip-local` to `videoagent-local`.
- Add a local VideoAgent sidecar contract with readiness, start/stop, task submission, polling, and asset-writing endpoints.
- Replace the fixed capability-card-first flow with an intent-first workflow: source media, natural-language goal, business scene, output package, generated plan, execution, and deliverables.
- Expose customer-facing capability groups for basic clipping, video understanding, creative remaking, and voice/audio processing without showing third-party runtime names.
- Keep FunClip only as a hidden migration fallback where needed; it must not define visible product capability or user copy.

## Impact
- Affected specs: `ai-clip-workbench`
- Affected code: `scripts/truegrowth-local-api.mjs`, `apps/web/src/workbench/WorkbenchShell.tsx`, `apps/web/src/workbench/workbench.scss`
- Runtime integration: new `/local-api/videoagent*` local API family, replacing visible `/local-api/funclip/tasks` usage in the clip workbench
