Cleanup is not running on self-hosted runners when using server config

[LP9688]

Describe the bug

On self-hosted runners, JFrog CLI server configs in ~/.jfrog/ are never cleaned up after a job when using JF_ENV_* config tokens for authentication. configJFrogServers() has two code paths — when using JF_ENV_*, it calls jf config import directly and never reaches getServerIdForConfig(), which is the only place SETUP_JFROG_CLI_SERVER_IDS is written via core.exportVariable. Since that env var is empty, shouldSkipCleanup() exits silently at debug level and ~/.jfrog/ is never cleaned. Stale server configs accumulate with every run.

For now it's possible to workaround this by manually setting JFROG_CLI_HOME_DIR env var

Current behavior

Here are the snippet for run logs for setup-jfrog-cli:

  Found JFrog CLI in cache. No need to download
  /***/_work/_tool/jf/2.91.0/x64/jf config import ***

And the post action:

Reproduction steps

1. Use a self-hosted runner
2. Authenticate via JF_ENV_1: ${{ secrets.MY_CONFIG_TOKEN }} (no JF_URL/JF_ACCESS_TOKEN)
3. Run the job — post-step skips cleanup silently
4. Check ~/.jfrog/ on the runner — stale server configs accumulate with every run

Expected behavior

Server configs imported via JF_ENV_* should be cleaned up by the post-step, the same way as configs added via JF_URL/JF_ACCESS_TOKEN.
