[FEATURE] Allow switching to dontAsk mode at runtime.

Problem Statement

Currently it is only possible to set the permission mode to "dontAsk" when starting a new claude session. I would like to be able to change into that mode in a session that is already open.

Proposed Solution

Add a new slash command that allows setting the permission mode to any of the available modes.

For example, /permission-mode dontAsk would set the permission mode to "dontAsk".

Alternative Solutions

The only workaround I know of is to close the clause session, then start claude again with claude --resume --premission-mode dontAsk.

This could also be solved by

• Allowing the set of permission modes in the cycle to be customized
• Adding dontAsk to the modes in the cycle
• Adding a new key binding to the TUI to switch to dontAsk mode.

However, while #32604 would be nice to have as well, I think having a slash command is the most flexible option. And scales the best if additional permission modes are added.

Use Case Example

I start a session in plan mode. claude starts asking permission to run a lot of commands while it is exploring. Many of these commands are find, ls, and grep commands, but are constructed in ways that don't match the allowed commands, and it _should_ be able to get the information it needs using tools it is allowed to use without prompting. I would like to switch to it being constrained to only using tools it is allowed to use without asking me, without having to restart the session.
