feat: add log rotation, non-blocking writes, and CLI log flags#398
Merged
Conversation
Replace synchronous single-file logging with tracing-appender for daily log rotation and non-blocking background writes. Add --log-level and --log-path CLI flags for controlling log verbosity and output directory. The --log-level flag applies only to project crates while keeping external dependencies at warn level. RUST_LOG still takes precedence. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
