[FEATURE] Dynamic Thought Bubble Windows (tmux-style multiplexer for task visibility)

Preflight Checklist

• [x] I have searched existing requests and this feature hasn't been requested yet
• [x] This is a single feature request (not multiple features)

Problem Statement

1. No visibility into parallel work - When Claude spawns background tasks, users can't see what each task is "thinking" until results return
2. Ctrl-O is clunky - Current system requires manual user action to check on background work
3. No persistent monitoring - Can't ask Claude to "keep an eye on" something (CPU, prices, news) while continuing other work
4. Guidance is hard - Users can't course-correct Claude early because they don't see reasoning until it's too late
5. Can't detach/reattach - If terminal closes or you switch machines, session is lost

Proposed Solution

Proposal

1. Task Thought Bubbles (temporary)

When Claude spawns tasks/agents, each gets a live "thought bubble" window showing internal reasoning:

2. Persistent Monitor Windows (long-running)

Natural language commands spawn watchers that run until dismissed:

System monitoring:

> "keep an eye on CPU usage while I run this backfill"

3. Session Attach/Detach (tmux-compatible syntax)

# Detach from session
Ctrl-B d

# List running sessions
claude ls
#  0: market_data_engine  (2 windows, created Mon Jan 20 09:15)
#  1: arb_bot             (1 window, created Mon Jan 20 11:30)

# Attach to session (short form, like tmux)
claude at -t 0
claude at -t market_data_engine

# Attach to most recent
claude at

# New named session
claude new -s debug_session

# Kill session
claude kill -t 0

Full commands (tmux-style):

| tmux | claude | action |
|------|--------|--------|
| tmux ls | claude ls | list sessions |
| tmux at -t 0 | claude at -t 0 | attach to session 0 |
| tmux new -s foo | claude new -s foo | new named session |
| tmux kill -t 0 | claude kill -t 0 | kill session |
| Ctrl-B d | Ctrl-B d | detach |
| Ctrl-B [ | Ctrl-B [ | scroll mode |
| Ctrl-B 1 | Ctrl-B 1 | focus window 1 |

Window Types

| Type | Icon | Behavior |
|------|------|----------|
| Task Bubble | 💭 | Temporary, auto-closes when task completes |
| Monitor | 👁️ | Persistent, runs until user dismisses |
| Alert | 🔔 | Pops to foreground when trigger condition met |
| Worker | 🔧 | Shows active work (file edits, builds, tests) |

Natural Language Commands

• "watch X" / "keep an eye on X" → spawns persistent monitor
• "alert me when X" → monitor with trigger condition
• "stop watching X" / "dismiss CPU monitor" → closes specific monitor
• "show monitors" → list all active watchers
• "detach" / "I'll be back" → detach from session
• "continue" → resume last session (alias for claude at)

Keyboard Navigation

| Key | Action |
|-----|--------|
| Ctrl-B d | Detach from session |
| Ctrl-B [ | Enter scroll mode (vim keys) |
| Ctrl-B 1, Ctrl-B 2, etc. | Focus specific window |
| Ctrl-B c | Close focused window |
| Ctrl-B n | Next window |
| Ctrl-B p | Previous window |
| ↑↓ in focused window | Scroll that window independently |

### Additional Context

Replace the current `Ctrl-O` system with a **tmux-like window multiplexer** that lets Claude dynamically spawn "thought bubble" panes for tasks, background processes, and persistent monitors. This gives users real-time visibility into Claude's reasoning and enab
les long-running watchers.
