fix(skills): stage SVGs that capture wrote into capture/assets/svgs/ (#3336)

`hyperframes capture` extracts inline SVGs into capture/assets/svgs/, 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.
stageAssets searched only capture/{assets,assets/videos,screenshots}, so 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.

Add the directory to the search list, and cover it with a test that fails
without the fix.

lib/assets.mjs is byte-identical across product-launch-video,
faceless-explainer and pr-to-video, so the fix lands in all three. Folding it
into hyperframes-core/scripts/lib/, where frame-packets-core.mjs already lives,
is a separate change.
