[Feature] oclite agent switching (/agents command)

[randomm]

Summary

oclite has no way to switch agents. It uses the default agent (likely Build). Need an /agents command similar to the full opencode TUI to allow agent selection.

Requirements

/agents command ✅ (implemented)

• List available agents
• Interactive selection (arrow keys + Enter in raw terminal mode)
• Switch the active agent for the current session

Agent visibility in prompt

• Show current agent name in the prompt prefix, e.g. Project Manager ❯ or build ❯
• User should always know which agent is active

Shift+Tab cycling

• Shift+Tab cycles through available agents (same as full opencode TUI)
• Quick way to switch without opening /agents dialogue

Selection UI ✅ (implemented)

• Arrow up/down to navigate
• Enter to select
• Escape to cancel
• Highlight current selection
