feat(hooks): suppress user prompt hook display

[tt-a1i]

Fixes #897

Summary

• add a per-hook suppress_tui_display option for UserPromptSubmit allow-output
• keep suppressed hook output injected into the model/context
• skip live hook.result events and transcript replay entries for suppressed chunks
• preserve mixed visible/hidden hook output order in context
• keep blocking UserPromptSubmit hook output visible
• update EN/ZH hooks docs and protocol origin parsing

Review

Ran a subagent review after implementation. It caught ordering/docs/protocol gaps; those are fixed now. Second pass found no blockers.

AI Assistance Disclosure

I used Codex to review the changes, sanity-check the implementation against existing patterns, and help spot potential edge cases.
