They still were read-only, but all Capabilities implicitly capture `cap` now.

- this of a Mutable type is exclusive in update methods, read-only elsewhere - a selection from a mutable type with read-only capture set is again read-only
Need to disable `associateWithMutable` for them.

Treat them analogous to calls of update methods
- whether we record x or x.rd also depends on the exclusivity in context - fix issue of missing updates for denotations when recording use of a path

| ```scala | ||
| class Cache[T](eval: () -> T): | ||
| private transparent var x: T = compiletime.uninitialized |

New doc page on mutability, split off from "Separation Checking".

Are there any tests from the mutability qualifiers paper that we could adapt to use here? Or from the paper that Ed presented at Scala Workshop? |
