Refactors the repeated setup-bazel steps in ci.yml into a local
composite action (.github/actions/setup-bazel-self-hosted).
This ensures a consistent configuration across all CI jobs, including:
- Disabling GitHub-backed caching to avoid redundancy and conflicts.
- Setting a unique output base per runner (${{ runner.workspace }}/.bazel)
to avoid server trashing.
- Configuring local persistent cache paths in the runner's home directory.
Future updates to the self-hosted Bazel configuration can now be
managed in a single place.

There was a problem hiding this comment.
If you can control which file this gets written to (e.g. self-hosted.bazelrc), we could use a try-import in the project's .bazelrc to import it if-and-only-if it exists.
In our .bazelrc, we'd add something like this:
# User bazelrc file
# =================
# See https://bazel.build/configure/best-practices#bazelrc-file
#
# Note: this should be at the bottom of the file, so that user-specified
# options override anything in this file
# (https://bazel.build/run/bazelrc#imports)
try-import %workspace%/self-hosted.bazelrc
