Redesign the Netclaw chat TUI

[Aaronontheweb]

Summary

• Add a quiet console grammar with no decorative transcript trim.
• Use native terminal scrollback for settled transcript content.
• Show structured thoughts, tools, parallel work, approvals, and sub-agent work.
• Add a multiline Composer, an Inspector, semantic copy, and double-Escape clear.
• Add structured session events and resume data through extend-only protocol fields.
• Add an opt-in Termina panel surface without a default behavior change.

Visual grammar

The design uses color, spacing, weight, and cell backgrounds.

Wide views use a two-cell left margin and a 120-column content cap.

The approval gate names the requester and the requested action.

The Inspector uses semantic event names and complete safe detail.

Design: docs/ui/TUI-002-chat-visual-grammar.md

Termina dependency

This change uses Termina 0.17.0-beta.6.
