Add more Famous Casualties to the graveyard

[dotsystemsdevs]

What

`src/lib/scoring.ts` has a `KNOWN_REPO_CAUSES` map with 6 hand-curated entries for famously abandoned repos (Atom, Bower, PhantomJS, etc.). The leaderboard in `src/components/Leaderboard.tsx` also has a static list of famous casualties.

We'd love more entries from the community.

How to contribute

In `src/lib/scoring.ts` — add entries to `KNOWN_REPO_CAUSES`:
```ts
'owner/repo': 'A short, witty, accurate cause of death',
```

In `src/components/Leaderboard.tsx` — add entries to the `FAMOUS_CASUALTIES` array with `fullName`, `cause`, `epitaph`, `deathYear`, and `language`.

Guidelines

• Repos must be genuinely abandoned or officially deprecated
• Causes should be factually accurate and written in the same dry, deadpan tone as the existing ones
• Keep causes under ~60 characters
• Good candidates: Parse, CoffeeScript, Flash SDK, Backbone.js, jQuery UI, Google+, Heroku free tier, SourceForge

Acceptance criteria

• At least 3 new entries added
• Each entry is factually accurate
• Tone matches existing entries
• `npm run lint` passes
