+Provides atomic audit event writing and reading for the project audit log.
+Each event is a single-line JSON object appended atomically. Events are

+
+Events include: timestamp, command, args, result (AuditResult enum),
+duration_ms, project_id, and optional details.
+
+Key guarantees:
+- Atomic append: no partial lines, no interleaving.
+- Every line is valid JSON (single-line object).
+- Events ordered by timestamp (ISO 8601 with timezone).
+- File only grows; never shrinks or overwrites existing entries.
