feat: add eventEmitter (#1693)

Adds an event emitter for hooking into method/property creation

fix: keep function/class names in bundle (#1701)

feat: remove unbundled sources (#1700)

* feat: remove unbundled sources

We used to ship two of everything:

- `lib` - the unbundled sources
- `chai.js` - the bundle

We then moved to only shipping `lib`, but this results in a slower and
slightly larger package.

This reverses that decision, such that we have only `index.js` (a
bundle, what was `chai.js` before), and no longer have `lib`.

* feat: move deps to dev dependencies

chore: update npm tag name (#1704)

fix: reintroduce bundle (#1699)

It turns out removing the bundle meant that chai loads a lot slower
thanks to module resolution, etc.

This reintroduces the bundle for 5.x, which will later become the only
entrypoint in 6.x (i.e. `lib` will no longer be shipped).

chore: remove bundled chai (#1694)

Removes the chai bundle such that `chai.js` is now an entry point just
like `index.js`.

We're keeping it around for now since there may be users directly
importing the file. It was already re-exporting what exists in
`index.js`, so this shouldn't be a breaking change.

chore: change `main` to point at chai directly (#1696)

Instead of using a top-level re-export, we can just point `main` at the
chai entrypoint directly.

Later in life, we can remove `index.js` and `chai.js`.

chore: use `files` for publishing (#1695)

Switches to using the `files` array so we can avoid publishing build
configs, etc.
