chore: delete the unreferenced snippets/home.jsx

[GigaHierz]

The hole, and the fix

snippets/home.jsx is 541 lines that nothing imports. Mintlify only renders a snippet a page imports, so it has never been served to a reader.

$ git grep -n "home.jsx" -- '*.mdx' '*.json' '*.jsx'
(no matches)

It is a stale duplicate of the CardGroup in home/celo.mdx. Keeping it has a real cost: every edit to that card deck has had to be made twice. #2301 hit this — the Lemonade→Luma swap and the Proof of Ship card removal both had to be applied to a file that renders nowhere.

It is also already rotten: its internal hrefs point at /about-celo/**, a tree renamed to /home/**, and at /about-celo/protocol/governance/voting-in-governance, which no longer exists.

What this does NOT do / residual risk

Deletes only. If someone wanted this deck as a reusable component, home/celo.mdx holds the current version and the file is one git revert away.

No redirect needed — AGENTS.md §2 covers pages, and this was never reachable. snippets/ is excluded from the orphan check by design, which is why the checker never flagged it.

Judgement calls

None. Discovered while auditing #2301's card-deck edits.

Issues

Closes: none. Follow-up from #2301.

Stacking / conflicts

Branched off main, independent. No other open PR touches snippets/.
