Subject: [PATCH] ci: disable uv cache in publish pipeline (#37364)

Disable `uv` dependency caching throughout the release workflow so
build, validation, PyPI publish, and GitHub release jobs do not restore
shared cache state.

Release jobs already pass the built distributions through explicit
artifacts; keeping dependency caches out of this path avoids
cache-poisoning risk and makes the existing pre-release validation
comment match the actual workflow behavior.
