This pull request introduces a new configuration variable, GRT_SEED, which allows users to specify a random seed for global routing. The changes include documenting the new variable in FlowVariables.md, defining its schema in variables.json and variables.yaml, and implementing the logic in global_route.tcl to apply the seed using set_global_routing_random during the global routing stage. There are no review comments, and I have no additional feedback to provide.

Was interested in running a seed sweep using the AutoTuner, so enabling the ability to set the GRT seed through a flow variable.
@eder-matheus is this the proper way to do this in GRT?
@maliberty FYI. I ran idecode through a six seed sweep and am running is_int through the same.
