[experiment] trying to short circuit relations in more places

sorta kinda like #56072

Use monocart for coverage reports, enable codecov

This is an experimental addition to `c8`, but works really well. The v8 HTML page it outputs can load checker.ts without batting an eye, and has sub-expression fidelity and can...

Completely remove Collection/ReadonlyCollection types

Split out of #51921 to constrain it to more valuable changes.

Ensure that Comparers only return -1, 0, 1 so results can be equated

12

I noticed this while working on cleaning up our (inconsistent) use of the binary search and ordered insert APIs. The binary search API requires that you have comparisons of _exactly_...

Fix good lints given by eslint-plugin-unicorn

[experiment] make tsc use the public API

Wacky test built on #55326 which makes `tsc` use the public API. Curious how bad the perf of this is. The below represents effectively the smallest our package is going...

Run bun in CI

Use iterators to avoid calculating all properties of UnionOrIntersectionType

54

For #51188 Profiling gave me this big chunk:  `getPropertiesOfUnionOrIntersectionType` is the biggest chunk. What I noticed was that `getReducedType` didn't actually need all of the properties; all it wants...
