[oclite] Complete regression - input not working after PR #144 merge

[randomm]

Symptoms

After merging PR #144, oclite is completely broken:

1. 30 second unresponsive period - MCP/plugin loading blocks UI
2. Input disappears on Enter - text typed vanishes when pressing Enter
3. No echo of user message - removed as 'bug fix' but was needed for feedback
4. Commands don't work - /help does nothing
5. No LLM responses - nothing happens at all

Expected

• Status updates during loading (like old oclite had)
• Input cursor only shown when ready
• User message visible after submit
• LLM responses streaming

Root Cause

Unknown - investigating. May have broken handleSubmit or session initialization.

Related

• PR fix(oclite): add text streaming and session error handling (#142) #144 introduced these changes
• Old oclite (pre-Ink) had working status updates - need to find in git history

Priority

Critical - TUI is unusable

Fixed in PR #147 - spinner, user display, help, MCP non-blocking
