feat(logging): Wave 1 - logging infrastructure complete

- Add logging config to config.yaml with level, auditRetention, appRetention
- Add 4 global exception handlers (uncaughtException, unhandledRejection, render-process-gone, child-process-gone)
- Create audit-logger.ts with JSONL format and 30-day rotation
- Define IPC logger channels (LOGGER_FORWARD) and preload API
- Define audit types (AuditAction enum, AuditEntry interface, AuditStatus enum)
- Add unit tests for audit logger

All typechecks passing. Wave 1 complete.
