docs: list BlueShell and Ghostty as apps on the site

[hanthor]

The TunaOS remote carries two terminals and neither was discoverable on the site. BlueShell (org.tunaos.BlueShell) has been live in the remote index since the repo moved into the org; stock upstream Ghostty (com.mitchellh.ghostty) lands with tuna-os/blueshell#83.

What's added

An app is listed in six places, not one — all six, for both apps:

• src/data/projects.ts — the /projects card, the /<app> landing page, /install?app=<id>
• src/pages/blueshell.tsx, src/pages/ghostty.tsx — ProjectLanding wrappers
• docs/blueshell/index.md (rewritten), docs/ghostty/index.md (new)
• sidebars.ts — entries under Apps
• src/pages/flatpak.tsx and docs/flatpak/index.mdx — both install catalogs

docs/blueshell/ becomes hand-authored

scripts/sync-org-docs.mjs overwrites docs/<slug>/ from each repo's README unconditionally, so without the HAND_AUTHORED entry the next sync reverts this page. That sync is also why the tree carried CONTRIBUTING.md and TUNA_OS_PROMOTION.md — a contributor guide and an internal migration runbook, neither user-facing. Both deleted; they stay in the repo they came from.

ghostty is in HAND_AUTHORED too — no such repo exists in the org, and the page documents an app TunaOS only republishes, so the entry keeps it safe if one ever appears.

Merge order

Merge after flatpak install tuna-os com.mitchellh.ghostty actually works — the pages present both install commands as working. BlueShell's is already true today.

static/flatpak/expected-apps.json is deliberately not in this PR: check-flatpak-remote.py fails on an app listed there but absent from the index, so both entries go in a follow-up once Ghostty's index entry exists.

CI status

Fixed (mine): Simplified Technical English — one 4-word noun cluster in docs/ghostty/index.md. .ste-budget is 0, so a single finding fails the job. Reworded rather than opted out; node scripts/ste-lint.mjs --summary is now clean.

Pre-existing on main, not introduced here — both verified by checking out origin/main and running the same commands:

Check	Evidence
Markdown Lint	main produces 4017 findings against a budget of 2834. This branch produces 4008 — nine fewer, because it deletes two synced files. The gate has been red since before this PR (see #368, same failure).
Node.js Syntax & Tests	Fails in check-install-commands on bluefin-cli, corral-vm and tavern — all in docs/bluefin-cli/index.md and docs/homebrew-tap/index.md, files this PR does not touch. Identical output on origin/main. These are tuna-os/homebrew-tap formulas that stopped resolving some time after 2026-09-03, when #368 last saw this job green.

Both look worth their own issue; neither blocks this PR.

Build tunaos-org, Internal Link Check, Workers Builds and both bootstrap jobs pass.
