fix: recover stalled status updates and remove CLI hard timeouts

[LIU9293]

Summary

• make status updates self-healing by posting an explicit error and switching to a fresh status message when updates fail
• classify timed out errors as timeout failures and add coverage for the new categorization path
• remove fixed per-request CLI timeout caps across Codex/Claude/Gemini/Kimi/Kilo/Qwen/Goose/Kiro and bump version to 0.1.19
