build: adjust source files structures (#136)

* build(typescript): disable from generating source map

* build(typescript): disable from generating declaration file

* build(typescript): modify source files to be compiled to the same dir

* build(typescript): modify distribution files to be generated to `dist` directory

* refactor: rename main entrypoint from `main` to `index`

* chore(git): specify attribute for `dist` directory instead of just `dist/index.mjs`
