ioanbudea-OAI f5297229c1 Record truncation metrics for accepted Guardian review inputs (#53628)
## What changed

Emit `codex.guardian.review.truncation` counts and `codex.guardian.review.truncation.bytes` histograms after successful input finalization. Aggregate observations across reduction stages by component and disposition (`truncated` or `omitted`), recording original, retained, and omitted byte totals. Exclude feasibility checks and failed retries from loss telemetry.

Keep blocking command-hook cancellation fixtures in the local environment and use double quotes for the Python command.

## Testing

Add metric-export tests covering aggregation across multiple reductions, separate truncation and omission totals, no loss metrics for rejected inputs, and no duplicate reporting on repeated finalization.
