Description
This PR rebalances the weekly RISC-V test partitions.
The weekly workflow previously split tests by fixed
ctest -I start,,strideindexing, which led to uneven runtimes and caused some partitions to exceed the 6-hour timeout.This change adds a weighted partitioning mode in the RISC-V test runner and initially uses runtime data from the last successful weekly run to distribute tests more evenly across the 10 weekly jobs, while keeping the existing smoke CI path unchanged.
After the initial rebalance, the runtime weights were refreshed once more using a validation run on my own fork, and the updated results are included here.
Tests missing from the collected runtime data are assigned a default estimated cost of 60 seconds, which keeps the partitioning logic stable for newly added or previously unseen cases.
