feat(logger): Add SetOutput and GetOutput for dynamic log redirection

[moshloop]

Implement atomic-backed output redirection for all loggers (root and named) without requiring handler reconstruction. Uses sync/atomic.Value to wrap io.Writer in outputBox, and a sharedOutput indirection writer that all handlers capture. This allows SetOutput to retarget existing loggers immediately and safely for concurrent callers.

Adds comprehensive test coverage including new logger redirection, existing logger retargeting, restore semantics, nil handling, and concurrent safety.

Also adds .gavel.yaml configuration to ignore false-positive secret detections in test fixtures and certificates.
