Install uv with mise in CI

Replace astral-sh/setup-uv with jdx/mise-action. CI now runs the uv
version in mise.lock, which is the version that local development uses.

The release workflow disables the mise cache, as it did for the
setup-uv cache (zizmor cache-poisoning).

Dependabot does not update mise.lock. To update uv, run
`mise upgrade uv` and commit mise.lock.
