- errcheck: check type assertions from sync.Pool.Get() in
loadbalance/balancer.go and matcher/radix.go

- revive: add doc comment for exported ReleaseMatchResult function
RadixTree.searchLongest previously allocated &MatchResult{} on the
heap every time it encountered a handler-bearing node during tree
traversal — potentially N allocations per lookup with only 1 surviving.
Changes:
- searchLongest now tracks best *RadixNode (stack pointer) instead of
allocating MatchResult at every handler node
- FindLongestPrefix allocates a single pooled MatchResult via sync.Pool
only when returning a match
- Add ReleaseMatchResult() for callers to return MatchResult to pool
- LocationEngine.Match releases pooled results after use
Result: 0 B/op, 0 allocs/op on tree traversal benchmarks (sequential
and parallel).
