[FEATURE] Agent view dispatch should support --allow-dangerously-skip-permissions

Preflight Checklist

Problem Statement

There's no way to set the permission mode when dispatching a session from the agent view input. If I want to run a session with --allow-dangerously-skip-permissions, it's just not possible from agent view.

The current workarounds are:

• Set defaultMode in settings to apply globally, which is too broad
• Set permissionMode in a subagent's frontmatter, which requires creating a subagent definition for what should be a one-off dispatch

Proposed Solution

Support --allow-dangerously-skip-permissions (or a shorthand) as a modifier when dispatching from the agent view input. Could be:

• A prefix/flag in the dispatch input itself
• A keybinding that toggles the permission mode for the next dispatch (e.g., Ctrl+P to cycle through modes before hitting Enter)
• A persistent setting within agent view that applies to all new dispatches from that session

The existing guard (requiring the user to have accepted bypass mode interactively at least once) should still apply.

Priority

Medium - Would be very helpful

Interactive mode (TUI) / Agent view

Additional Context

Related to #39889, which covers the same gap for mobile/desktop dispatch. This is specifically about the CLI claude agents TUI.
