* chore(deps): bump to Astro 7 + Vite 8, pin direct deps to exact versions

Consolidates dependabot PRs #8, #9, #10, #11 into a single verified upgrade:
- astro 6.4.5 -> 7.0.3 (major; Vite 7 -> 8, Rust compiler)
- @tailwindcss/vite -> 4.3.1, tailwindcss -> 4.3.1 (pinned exact)
- transitive: devalue -> 5.8.1, esbuild -> 0.28.1, vite -> 8.1.0

Verified locally: bun run build passes (15 pages). No v7 breaking-change
patterns in codebase (no astro:transitions internals, no src/fetch.ts,
no @astrojs/db, View Transitions use string-literal events). Node 24 (>=22.12 OK).
Both bun.lock and package-lock.json synced.
