ci: improve workflow reliability and performance (Phase 1)

- Replace deprecated jakejarvis/wait-action with native sleep command
- Add concurrency control to cancel outdated workflow runs
- Add timeout-minutes to all jobs to prevent infinite hangs
- Standardize test concurrency flag across all package workflows

These changes improve CI reliability and reduce resource usage by
preventing stuck jobs and canceling redundant runs on new commits.
