Add curated catalog entries for popular MCP servers

[tsouth89]

The catalog is a hand-verified list of popular MCP servers that become one-click "Add" buttons in src-tauri/src/catalog.rs. Growing it is one of the easiest, highest-value ways to contribute.

If there's a real, working MCP server you use that isn't in the catalog, add it. The guide is in CONTRIBUTING.md: one http() or cmd() line plus a category, and the tests check it automatically.

Comment with the server you're adding to avoid overlap. See the comments below for the running list of what's already in, so you don't dupe.

Acceptance

• New entry in catalog.rs with a category (and a credential hint if it needs a key).
• cargo test --manifest-path src-tauri/Cargo.toml catalog passes; the server connects and exposes tools when added.

Hi @tsouth89 can I work on this issue?

[tsouth89]

Yes, and your BoltAI PR is in and clean, so this is a perfect next one.

One rule matters most here, the one the issue flags: only add a server you've actually run and seen connect and list tools. An entry that looks right but doesn't work is worse than none, it breaks someone's first launch. So pick from things you've genuinely used.

What's already in, so you don't dupe (24): Stripe, GitHub, Vercel, Sentry, Cloudflare Docs, AWS, Supabase, Neon, PostgreSQL, Notion, Linear, Atlassian, Asana, Slack, Resend, Context7, DeepWiki, Hugging Face, Brave Search, Figma, Filesystem, Fetch, Git, Playwright.

Still-open gaps if you've used any: MongoDB or Redis, GitLab, Grafana or Datadog, Firecrawl or Exa, Shopify or PayPal, HubSpot, Google Drive or Maps. Pick whatever you've actually run.

Format is two helper closures at the top of curated():

Hosted: http("Name", "short description", "https://endpoint", "https://homepage")

Local stdio: cmd("Name", "short description", "npx", &["-y", "the-package"], &["REQUIRED_ENV"], "https://homepage")

Drop your line into the matching category in the vec![]. Env vars are names only, never values, and keep the description short like the existing ones. You've got the full list above, so dedupe against it, make sure it actually connects, and open the PR, no need to clear the pick with me first.
