feat(pipeline-run): surface API HTTP failures as clean errors

[arseniy-pplx]

Summary

• add a shared HTTP-error formatter and surface_http_errors context manager for SDK commands
• report API status, reason, method, URL and a bounded, whitespace-collapsed response body as one-line command errors
• wrap pipeline-run manager API calls (status, details, cancel, graph-state, logs, list/search, export, submit) and annotation commands while preserving client-level recovery, post-submit run recovery, and fallback behavior
• report per-run graph-state failures with the same formatted message in each result's error field

Context

Pipeline-run SDK commands currently leak raw requests tracebacks when the API returns a non-2xx response. The command layer already converts PipelineRunError to a clean non-zero exit; this change makes HTTP failures on sdk pipeline-runs commands cross that boundary instead. Client-internal recovery (the 404 run-id -> execution-id fallback, submission-id run recovery after a failed submit) keeps handling the statuses it can; only unrecovered errors are formatted.

Behavior note for downstream hook subclasses: on_poll_error and on_submit_error now receive PipelineRunError (with the original requests.HTTPError chained as __cause__) instead of the raw HTTPError when an API call fails with an HTTP status error. Non-HTTP submit errors reach on_submit_error unchanged.
