Add a social preview banner

[ChrisonSimtian]

GitHub was serving the auto-generated card (opengraph.githubassets.com) for this repo, while the framework has a custom upload — so a link to this repo looked unrelated to it.

Changes

• .assets/fallout-social-preview.svg — source, adapted from the framework's.
• .assets/fallout-social-preview.png — 1280×640, what GitHub serves.
• .vscodeignore — keep .assets/** out of the .vsix; it's repo branding, not an extension asset (media/ holds those).

Notes

Same layout, palette and trefoil as the framework's banner. Two lines differ, because copying it verbatim would have made this repo claim to be the framework: the tagline reads "Build targets, inside your editor", and the footer is this repo's URL.

Uploading is manual — Settings → General → Social preview. GitHub has no REST API for it, so merging this doesn't change the card on its own; it only tracks the source so it can be regenerated instead of recovered from a screenshot.

Regenerate with:

rsvg-convert -w 1280 -h 640 -o .assets/fallout-social-preview.png .assets/fallout-social-preview.svg

Estimated code review effort: 1 (Trivial) | ~2 minutes

Merge Risk: ⚪ Minimal · up to 9c939

This change adds social preview artwork and keeps it out of the packaged extension; it does not alter extension behavior, so no actionable merge-blocking risk remains.
