Guard callback drain in Strict/Lax pools; avoid fireCallbacks()->release() re-entry. Prevents StackOverflowError under fast-fail connect/retry; no semantic change.

Fix StackOverflowError from synchronous re-entrant callback dispatch in pools.
Add re-entrancy guard, factor releaseInternal, make drain iterative; mirror in LaxConnPool.
Preserves synchronous semantics; completions still drained inline.
Add regression tests: pre-fix overflows; post-fix iterates to high counts.
