> CAMEL-24860 restores the previous routes after a failed reload by loading the 
> previous sources again from disk, which works when the failing file is not 
> the only one. When it is the only route file, the good version is gone from 
> disk, and the app runs without routes until the next successful save, with 
> the log saying so. In the camel-jbang-mcp stepwise benchmark every HTTP 
> example is one file: a write that fails to load (an invalid file written with 
> validate=false, CAMEL-248xx) takes the whole app down for the rest of the 
> step, and the REST endpoints answer 404 while the model reads the log.
> Keep the last successfully loaded route definitions (the model objects, not 
> the file) per source, and on a failed reload of that source add them back, so 
> the app keeps answering with the previous version of the file and the log 
> says "Reload failed ...; the previous routes of <file> are still running".
