Feature request: Toggle permission bypass mode mid-session

Feature Request

Add the ability to toggle dangerously-skip-permissions mode during an active session, rather than only at startup.

Proposed UX

• /permissions bypass on or a custom slash command to enable bypass mode mid-session
• /permissions bypass off to disable it and return to normal permission prompts

Use Case

Sometimes you start a session in normal mode but realize partway through that you want to enable bypass mode (or vice versa). Currently, you have to exit and restart Claude Code with the --dangerously-skip-permissions flag or modify settings.json.

Being able to toggle this mid-session would save time and preserve conversation context.

Current Behavior

Permission mode is locked at session startup via:

• --dangerously-skip-permissions CLI flag
• permissions.defaultMode in settings.json

There's no way to change it once a session is running.
