feat: make feed directory search-first and easier to browse

[gildesmarais]

Summary

• redesign the feed directory so search and ready-to-use feeds appear immediately
• demote instance selection into supporting context and clarify default parameter handling
• tighten feed rows around source URLs, copy/rss actions, and mobile scanning

Validation

• npx prettier --check src/components/FeedDirectory.astro src/components/feed-directory.js src/content/docs/feed-directory/index.mdx
• npm run build

Pull request overview

Redesigns the Feed Directory documentation page and component to be search-first, with improved instance selection UX and tighter feed rows (source link, RSS action, copy action).

Changes:

• Replaces most of the MDX page intro with the FeedDirectory component and updated instance/contribution links.
• Refactors the feed directory client JS: search result/empty state handling, instance URL editor + hash persistence, parameter form toggles, and copy-to-clipboard.
• Rebuilds the FeedDirectory.astro markup/CSS for the new layout (search header, instance summary/editor, feed rows, and empty state).

<script src="./feed-directory.js"> is a URL relative to the rendered page, but feed-directory.js lives under src/components/ and there is no corresponding file in public/. Unless this script is emitted elsewhere, the browser will likely 404 this request and the directory will lose its JS behavior (search, instance switching, copy). Consider bundling it via Astro/Vite (e.g., import it as a module) or moving it into public/ and referencing it with a stable absolute path.

I checked the built output before and after 45105d0. Astro is emitting the component script as a bundled module asset under dist/_astro/FeedDirectory...js, so this relative src is being compiled rather than requested from /feed-directory/feed-directory.js. Leaving this thread open if you want the component switched to an explicit imported pattern anyway.
