fix(ci): cap stalled unit jobs at 45 minutes

[marius-kilocode]

CLI unit subprocess leaks can leave the unit matrix job running until GitHub's default six-hour timeout, consuming runner capacity and blocking the required test check.

Cap the unit job at 45 minutes. Healthy runs finish well below that ceiling, while a leaked subprocess now fails within a bounded window instead of retaining a runner for hours.

This is intentionally a containment measure, not a test-runtime optimization. Follow-up work should harden process-tree cancellation in the CLI test runner and profile the Windows TUI plugin lifecycle slowdown.
