Adam Perry @ OpenAI d5b29951ac Centralize retry decisions and delays in CodexErr (#46540 )

## What changed

Replace `is_retryable()` with `retry_delay(retry_count)`, which returns `None` for terminal errors and a delay for retryable errors. Prefer server advice when present; otherwise use exponential backoff with jitter. Keep `server_retry_delay()` for callers that need only the server-provided delay.

Route sampling and remote compaction errors through the shared response stream handler, which now checks retryability and obtains the delay together. Preserve server-only retry timing when the retry budget is exhausted.

## Testing

Add coverage for attempt-dependent backoff, zero-duration server advice, and terminal errors that remain non-retryable despite server advice. Update API mapping and provider tests to use the combined retry API.

codex-client

Higher-level request policy layered on codex-http-client without any Codex/OpenAI API awareness.

Provides retry utilities (RetryPolicy, RetryOn, run_with_retry, backoff) that callers plug into for unary and streaming calls.
Supplies the sse_stream helper to turn byte streams into raw SSE data: frames with idle timeouts and surfaced stream errors.
Defines the request telemetry callback used by higher-level clients.
Re-exports the low-level HTTP types temporarily so consumers can migrate to codex-http-client incrementally.
