Add /side conversations (#18190)

Browse Source 
The TUI supports long-running turns and agent threads, but quick side
questions have required interrupting the main flow or manually
forking/navigating threads. This PR adds a guarded `/side` flow so users
can ask brief side-conversation questions in an ephemeral fork while
keeping the primary thread focused. This also helps address the feature
request in #18125.

The implementation creates one side conversation at a time, lets `/side`
open either an empty side thread or immediately submit `/side
<question>`, and returns to the parent with Esc or Ctrl+C. Side
conversations get hidden developer guardrails that treat inherited
history as reference-only and steer the model away from workspace
mutations unless explicitly requested in the side conversation.

The TUI hides most slash commands while side mode is active, leaving
only `/copy`, `/diff`, `/mention`, and `/status` available there.
