refactor: extract seed provision scripts to dedicated directory

Move bootstrap, default, and inform scripts from inline template
strings in lib/init.ts to standalone files under seed/, loaded via
an esbuild text-loader plugin. Add type-checking (provisions.d.ts,
tsconfig.json) and ESLint config for the seed scripts. Set tsconfig
module to Preserve to support import attributes.
