[oclite] TUI fundamentally broken - commands don't work, no LLM output

[randomm]

Critical Issues (from user testing Feb 6)

1. [EVENT] debug logs polluting output - console.error debug logging mixed with TUI
2. Ink not controlling terminal - all output as plain text, not TUI rendering
3. Response text duplicated - 'Hello! How can I help you today?' appears twice
4. TUI resets after long response - messages swallowed, banner re-appears
5. 10-15s unresponsive gap after spinner completes

UX Issues

6. User message stuck to prompt line (no separation)
7. Model/submodel need selection modal (like opencode TUI)
8. Need Shift+Tab to cycle agents (build/plan/pm from config)

Root Causes Identified

• console.error() debug logging in useSDKEvents.ts
• Ink patchConsole not enabled
• Delta vs full text handling causes duplication
• Welcome banner re-renders on every state change
• MessageList renders role as raw text
