refactor(types): use dts-buddy to generate types with map (#751)

* refactor(types): use dts-buddy to generate types with map, cleanup type definitions and tsconfig

* chore: update generated types

* fix: use .d.ts for type imports

* fix: ignore .changesets/pre.json to prevent format check fails on main after release merge

* fix: move types inside import condition to avoid masquerading as cjs warning

* fix: types

* bump dts-buddy

* fix: regenerate types

* fix: use correct type Options for plugin function arg

* fix(types): reexport index.js from public.d.ts to ensure types and functions are properly exported through module declaration generated by dts-buddy; move dynamicCompileOptions to PluginOptions, rename SvelteOptions to SvelteConfig

* fix: update lockfile

* Update .changeset/metal-olives-wait.md
