pub fn init_tracing(log_level: &str, log_format: &str)Expand description
Initializes the global tracing subscriber, panic hook, and log bridge.
Must be called exactly once, before any tracing events are emitted.
After this call, panics on any thread produce tracing::error! events,
and log crate events from dependencies (refinery, ureq, ort) are
forwarded to the tracing subscriber.
Stderr is always the agent-facing diagnostic stream. File logging is
optional via XDG log.to_file (GAP-SG-108).
