Improve routing， Occasionally it is found that the routing file cannot be automatically reconstructed

[1057105012]

It is hoped that the dashboard supports adding, deleting, modifying, and rebuilding routes. At the same time, it speeds up the generation of speed components when adding new routes. Currently, there is a delay on low-end machines.

Currently, it is found that creating routes is not convenient. The second is that when routes are modified and copied, the automatic generation function sometimes occurs. If an error is reported, it can only be manually deleted and rebuilt. I hope to improve it

The specific ideas are as follows

1. Each file corresponds to a checksum
2. Determine which files may be suspected to be modified by accessing the latest timestamp.
3. Monitor the addition, deletion and modification of folders, and reconstruct the virtual file list maintained in memory. Then convert to router file. If any step fails, the update of the virtual file list will be canceled and the latest timestamp will be compared to confirm which file changes are behind
4. Check the checksum of all files and compare the virtual file list in the background every 3 minutes. If there are inconsistencies, rebuild the target route.
5. The page provides manual refresh routing just in case. These operations are performed in queues. Each routing route is executed sequentially by an independent thread
6. If it is detected that the target routing tree does not exist, a new one will be automatically created. All routing routes are mainly defined in files. If the routing tree exceeds the limit, redundant routes will be automatically deleted.
