Code-Level Confirmation

• src/media/fetch.ts now routes non-2xx failures through bounded prefix reads instead of buffering the whole error body.
• src/media/read-response-with-limit.ts enforces capped reads and truncates oversized snippets before surfacing failure text.

OpenClaw thanks @YLChen-007 for reporting.
