Add contributor attribution to canvas extension cards

[ashleywolf]

Every canvas extension on the extensions page now credits the person who built it, the same by {author} line that plugins and samples already show.

What changed

• Added a standard npm author field ({ name, url }) to each extension's package.json, and an author field to the Coffilot entry in external.json.
• eng/generate-website-data.mjs reads the author (npm string or object form) and emits it on each extension in the generated extensions.json.
• The card renderer (extensions-render.ts) and the details modal (extensions.ts) render the name as a link to the contributor's GitHub profile.

How I picked each contributor

I traced each extension to the author of its original PR or first commit on staged, excluding the Copilot co-author, since main is published by a bot and loses that history.

Extension	Contributor
accessibility-kanban, color-orb, diagram-viewer, feedback-themes, gesture-review, where-was-i	@aaronpowell (#1900)
backlog-swipe-triage, release-notes-showcase	@jamesmontemagno (#1987)
arcade-canvas	@DanWahlin (#2031)
chromium-control-canvas	@AndreaGriffiths11
coffilot (external)	@jdubois

For arcade-canvas and chromium-control-canvas I kept the name each author already set in package.json and only added their profile URL.

Verifying

• npm run website:data emits an author for all 11 extensions (10 local + 1 external).
• astro build passes with no type errors.
• Local preview shows the by {name} profile link on every card and in the details modal, for both local and external extensions.

The generated website/public/data/extensions.json is gitignored, so this PR only touches source.

could we move this to the canvas.json file, as that's where we're storing the metadata about the canvas

[ashleywolf]

Moved it. author {name, url} now lives in each extension's canvas.json (and external.json for the external one), read by the generator — package.json is untouched now.

Two related changes while I was in there:

• Cards and the details modal show the GitHub @handle (derived from the profile URL), with the full name on hover.
• Wrapped the author URL in escapeHtml() before it goes into the href, per Copilot's note.

Pushed as one clean commit (66ef3f6). Re-requesting your review when you have a sec, @aaronpowell.
