[FEATURE] Non-interrupting way to add directories mid-session

Problem

When Claude is working on a task and you realize you need to add another directory to the context, you must:

1. Interrupt Claude mid-task
2. Run /add-dir ../some-directory
3. Tell Claude to continue (e.g., "sorry to interrupt, please continue")

This causes:

• Loss of focus/momentum for the AI
• Unnecessary context pollution with the interruption exchange
• Poor UX when you just want to expand the workspace

Current Workaround

Pre-configure directories in .claude/settings.json:

{
  "permissions": {
    "additionalDirectories": ["../other-project/"]
  }
}

However, this doesn't help when you discover mid-session that you need a directory you didn't anticipate.

Proposed Solutions

Option A: Allow /add-dir to work silently without requiring a response from Claude. The directory would be added to the context, and Claude would continue its current task uninterrupted.

Option B: Add a keyboard shortcut or side-panel action to add directories that doesn't inject into the conversation flow.

Option C: Allow the user to queue commands (like /add-dir) that execute without interrupting the current generation.

Expected Behavior

Adding a directory mid-session should not require interrupting Claude's current task or polluting the conversation with "please continue" messages.
