Conversation
Optimizes `listAllRegions` across service, domainmapping, job, and workerpool packages by replacing mutex-guarded concurrent appends to a shared slice with a lock-free, pre-allocated map-reduce pattern using a slice of slices (`[][]T`). This completely eliminates lock contention during parallel execution and reduces heap allocations by ~26% due to single flat-slice pre-allocation.

This PR optimizes the multi-regional listing operation (
listAllRegions) acrossservice,domainmapping,job, andworkerpoolpackages.💡 What
sync.Mutexand shared slice appending with a lock-free, pre-allocated[][]Tslice of slices.🎯 Why
Listing resources across all supported GCP regions (24+ regions) concurrently was previously bottlenecked by mutex locking and logarithmic slice reallocation overhead.
