Current evaluation

Enhancement to run managed builds for multiple build-plan platforms in parallel instead of serially. Triaged by a maintainer with an internal Jira ticket (CRAFT-4779), but unimplemented; code still loops the build plan serially.

Suggested action: keep open

Reason: The issue is properly triaged (labels 'Status: Triaged', 'Type: Enhancement', filed by maintainer lengau) and the requested behavior is confirmed still absent: _run_manager_for_build_plan in craft_application/commands/lifecycle.py iterates the build plan with a plain serial for-loop calling provider.run_managed per item. It is inactive (~348 days, only a bot comment linking Jira CRAFT-4779), but not obsolete, so it should stay open rather than be closed as stale.

Issue body

### What needs to get done If the build plan has multiple items, the manager instance should be able to start up the managed instances simultaneously and perform multiple builds simultaneously. ### Why it needs to get done These builds often don't fully utilise your machine's resources, so doing them in parallel can help fix that.
