Refactor `astro` export map, add `source-map-support` (#161)

* fix: add svelte plugin for esbuild, remove precompiled svelte components

* refactor: public export map, public types

* feat: add source-map-support to common code paths

* chore: move new "exports" to "imports" map, add internal types

* Include outPath in error logging for bad load status, and drop error stack (#163)

* Include outPath in the error logging for bad load status

* Discard error stack since it seems not useful

* feat: improve build error logging

* refactor: use object param for writeResult
