chore: upgrade Astro from 5 to 7

[nicodes]

What changed

astro ^5.18.1 → ^7.2.8 (resolved to 7.3.3). @astrojs/check ^0.9.10 and typescript 6 stay as-is (0.9.10 is confirmed compatible with astro 7 — ctcalc's PR #18 evidence). No source, config, or workflow changes were needed; bun.lock regenerated.

Migration-guide findings (v6 and v7 guides both read in full, checked per content area)

• astro.config: empty defineConfig({}) — no experimental flags, no Vite config (v6 Vite 7 / v7 Vite 8 N/A), ESM .mjs (CJS-config removal N/A), no i18n.
• Components/layout (Entry.astro, Full.astro): only Astro.url.pathname / Astro.generator in component frontmatter (unaffected), one <script type="application/ld+json"> (not a processed client script; v6 script-order change N/A). The v7 Rust compiler accepted every template — no unclosed-tag errors, and no previously auto-corrected invalid nesting (verified via rendered output, below).
• Integrations: none. Adapters: none. Middleware/endpoints: none (no .ts/.tsx/.jsx in src at all).
• getStaticPaths / dynamic routes: none — three static pages only.
• md/mdx: none — Sätteri default processor and heading-ID changes N/A; no remark/rehype plugins.
• Content collections: none (no src/content, no content.config.ts) — legacy-collections removal and Zod 4 N/A.
• src/fetch.ts: does not exist — the v7 reserved-name collision does not apply.
• Experimental flags: none used (v6: csp/fonts/preserveScriptOrder/staticImportMetaEnv/etc.; v7: logger/queuedRendering/rustCompiler/advancedRouting/cache).
• Node version: v6 requires Node 22.12+; engines already says >=22.12.0.
• compressHTML: 'jsx' (v7 default): verified by rendered-output comparison, below.

Local gates (bun 1.3.10)

• bun run typecheck: 7 files, 0 errors, 0 warnings, 0 hints.
• bun run build: 3 pages built; CI assertions replicated (index/devtools/games pages non-empty; no *.js in dist).
• Rendered-output equivalence vs the astro-5 build (baseline diffed): visible text nodes identical on all three pages (same node counts; every differing node differs only by whitespace-run normalization — the compressHTML 'jsx' default). CSS verified equivalent: declaration multisets identical after normalizing the new scope-hash cids; remaining deltas are serializer cosmetics only (transparent→#0000, dropped calc() inside min() (implied), omitted default ease in transition shorthand, case-normalized keywords, *:before selector normalization). No shorthand/longhand overlaps that declaration reordering could flip.
