Retarget instructions/astro.instructions.md to Astro 7 and
instructions/svelte.instructions.md to Svelte 5 / SvelteKit 2, fix
outdated APIs, add current stable feature guidance, and trim non-code
(setup, deployment, testing-workflow, recap) content so each file
focuses solely on code structure and best practices.
Regenerated docs/README.instructions.md via npm start.
