Pull request overview
This PR adds configuration options to make LiveDebugger startup more resilient in host applications by (1) optionally auto-selecting an available TCP port and (2) optionally preventing endpoint startup failures from crashing the entire application.
Changes:
- Introduces
LiveDebugger.App.Web.EndpointStarterto optionally ignore endpoint startup errors (:ignore_startup_errors). - Adds
:auto_portsupport to scan for the next available TCP port and propagates the resolved port into generated tags. - Documents the new port-conflict handling options in
docs/config.md.
