Be the app people find when they describe their problem

List my web app on Eudler.

1. Read this project and work out what the app does.
2. Draft a listing: name, public URL, a one-sentence summary of
   the problem it solves (60-160 characters, plain words, no
   feature lists), who it's for, and pricing (free, freemium,
   trial or paid).
3. Show me the draft and wait for my OK.
4. Submit it: POST https://eudler.app/v1/apps with the header
   "Authorization: Bearer $EUDLER_KEY" and the listing as JSON.
5. Add /.well-known/eudler.json to the site so Eudler can
   verify it's mine.

Set up Eudler listing sync for this project.

1. Create eudler.json in the repo root with: name, url, summary,
   audience, pricing.
2. Serve a copy at /.well-known/eudler.json so Eudler can verify
   the site.
3. Add a deploy step that runs:
   curl -X POST https://eudler.app/v1/apps \
     -H "Authorization: Bearer $EUDLER_KEY" \
     -H "Content-Type: application/json" \
     -d @eudler.json
4. Store EUDLER_KEY as a CI secret. Never commit it.
5. Tell me what you changed.
