feat: config improvements (#53)

* feat: move defineMcFlyConfig to @mcflyjs/config

* feat: move defineMcFlyConfig to config package

* feat: programmatically build nitro dev server

* chore: bump versions

* feat: spread nitro config if exists

* chore: use nitro build programmatically

* feat: use nitro programmatically in prepare command

* feat: expose types for NitroConfig & McFlyConfig

* feat: use c12 to resolve mcfly config

* fix: too many symlinks

* chore: skip tests for now

* test: cheating

* test: cheating

* chore: update pnpm-lock
