Migrate developer/bin/list_running_app_ids to a proper Homebrew command at cmd/list-running-app-ids.rb, as part of #174192.

[Copilot]

Pull request overview

Migrates the developer/bin/list_running_app_ids standalone script into a proper brew tap command (list-running-app-ids), and updates existing tooling to call the new command as part of #174192.

Changes:

• Removed the legacy developer/bin/list_running_app_ids script.
• Added cmd/list-running-app-ids.rb implementing the new brew list-running-app-ids command.
• Updated developer/bin/list_ids_in_app to use the new command for “is this bundle id running?” checks and documentation examples.

When a is provided, the command sets Homebrew.failed = true but does not explicitly return/exit non-zero. Within this repo’s other tap commands (e.g. cmd/find-appcast.rb), failure is indicated by the method’s boolean return value rather than setting a global flag. Please ensure brew list-running-app-ids <bundle-id> reliably exits with a non-zero status when the bundle id is not running (so callers like developer/bin/list_ids_in_app can detect it).
