Make CLI build workflow always trigger on PRs with path-change detection (#464)

Remove path filters from pull_request trigger so the workflow runs on every
PR to main. Add a check-changes job using dorny/paths-filter to detect
CLI-relevant file changes. The build-and-validate job is conditional on
that output, so it skips cleanly when no relevant files changed — making
this workflow suitable as a PR required status check.
