Surprised me, but removing destructuring helped.

"ESCAPED" -> "escape" arguably reads better in an error (Unexpected escape at index 12). That said, I don't think type would ever show in an error anyway, the only unexpected token is "end".

All these types are also internal only, never exposed, so renaming them is safe (only the error changes for "Unexpected END").

Realized using the same token type strings would improve compression and found some other small byte savings. At this point the next largest size improvement would be moving to ESM so I think this is the last bump available, but I welcome PRs that remove more bytes in the minified output without affecting readability.
