tongzhou wang 854cbb2fd4 Make tool-result telemetry limits configurable (#39779)
## What changed

- Add `otel.tool_result.max_bytes`, defaulting to 2048 bytes, to control the
  text included in `codex.tool_result` logs independently of model-visible
  output limits.
- Apply truncation centrally when emitting telemetry, preserve UTF-8
  boundaries, and report whether the logged output was truncated.
- Record typed tool names and namespaces, agent names, and process-local result
  sequence numbers while keeping tool arguments and output out of trace events.

## Testing

- Cover configuration propagation, UTF-8-safe truncation, raw tool-output
  logging, and log/trace event routing and fields.
