fix(skills): stage SVGs that capture wrote into capture/assets/svgs/

[miguel-heygen]

What

stageAssets now searches capture/assets/svgs/, so an SVG that hyperframes capture extracted can be staged into assets/ like any other captured asset.

Why

capture writes inline SVGs to capture/assets/svgs/ (packages/cli/src/capture/assetDownloader.ts), and the capture manifest advertises them to the agent as assets/svgs/<name>.svg. So a frame names one in asset_candidates exactly the way it names a screenshot.

The staging search list covered capture/{assets,assets/videos,screenshots} only. Every captured SVG resolved to nothing: logged as a non-fatal anomaly, and the frame 404'd the brand mark it had been told to use. Found running /product-launch-video end to end.

How

One entry added to captureDirs.

lib/assets.mjs is byte-identical across product-launch-video, faceless-explainer and pr-to-video, so the fix lands in all three.

Not covered: the triplication itself. Folding lib/assets.mjs into hyperframes-core/scripts/lib/, where frame-packets-core.mjs already lives, is a separate change and not in this PR.

Test plan

New skills/product-launch-video/scripts/stage-assets.test.mjs, covering both the captured-SVG case and an asset that genuinely exists nowhere (so the anomaly path is still exercised).

Verified it fails on the parent commit and passes here.

Manual: a fixture project with a captured SVG, a screenshot and a root capture asset, all three named by one frame.

• Before: ✓ staged 2/3 asset(s) into assets/ plus asset "brand-mark.svg" named by a frame but not found under capture/

• After: ✓ staged 3/3 asset(s) into assets/

• Unit tests added/updated

• Manual testing performed

• Documentation updated (if applicable)

Approve — one-line fix applied identically across all three triplicated copies. The new capture/assets/svgs/ entry sits naturally alongside the existing capture/assets/videos/ subdir entry, the comment is updated to match, and the test covers both the positive case (SVG + screenshot staged together) and the negative (absent asset still surfaces an anomaly). No issues.
