docs(site): inject version from Cargo.toml at build time

astro.config.mjs reads [workspace.package].version once and exposes it
via Vite's define as __LIP_VERSION__; src/version.ts re-exports it as a
typed constant. Hero badge, terminal demo, and footer in index.astro
now reference {version} instead of a hardcoded string, so future tag
bumps only require Cargo.toml + a Vercel rebuild.
