[Bug] Missing `rate_limits` field in statusline JSON payload

Bug Description
Bug: rate_limits field missing from statusline JSON payload in 2.1.119 The statusline docs (https://code.claude.com/docs/en/statusline.md) document rate_limits.five_hour.used_percentage and rate_limits.five_hour.resets_at as available fields for Pro/Max subscribers after the first API response. In 2.1.119 the entire rate_limits key is absent from the JSON piped to the statusline command, even mid-session with cost > $0 and many API calls made. The payload only contains: session_id, model, workspace, version, cost, context_window, output_style, effort, thinking, fast_mode, exceeds_200k_tokens. Repro: write a statusline script that dumps stdin to a file, then inspect the dump after a few turns. No rate_limits key appears. Impact: custom statuslines that show 5-hour usage % and reset countdown silently lose that section. Model: claude-opus-4-7[1m], plan: Max.
