Detailed Description

POSIX rte_log OSAdapter: non-blocking best-effort write to stderr (ADR-018 section 2.3), matching REQ-OAL-LOG-001 ("best-effort, non-blocking, must never affect caller control flow").

Known simplification (stated in ADR-018): no queue, no separate drain thread - a direct fwrite() to stderr. stderr writes are typically fast enough in practice not to violate the non-blocking intent for a first cut, but a deployment wanting a hard non-blocking guarantee (stderr could be a slow pipe/tty under adversarial conditions) should route through a lock-free ring buffer drained by a dedicated low-priority thread instead. write() failures are silently ignored, per REQ-OAL-LOG-001 - logging must never affect caller control flow, so there is nothing meaningful to report back to the caller here.
