/resume from "All" scope doesn't update cwd and tools still operate from original directory

[niklaas]

What happened?

When resuming a session from a different workspace using the "All" scope in /resume (Tab to toggle), the session's conversation history loads correctly, but the working directory is never updated. Tools continue to operate from the directory pi was originally launched from, not the directory the resumed session belongs to.

The session header stores the original cwd (e.g. {"type":"session","cwd":"/path/to/other/project",...}), but switchSession() in agent-session.ts only restores the model and thinking level instead of reading and/or applying the session's cwd.

Steps to reproduce

1. Launch pi from /project-a
2. Open /resume and press Tab to switch to the "All" scope
3. Select a session that was created in /project-b
4. Ask the model to list files or run any bash command
5. Observe that results reflect /project-a, not /project-b

Expected behavior

Resuming a session from a different workspace should switch the working directory to the cwd stored in that session's header, so that tools operate in the correct project directory.

did a spike on this, it's actually super tricky. will need some time to fix, requires some architecture changes (for the better).

Thanks for considering. Let me know if I can be of any support.

this is now fixed on a local branch, will be on main tomorrow hopefully.

Does this also make it so reload() changes cwd and picks up the new AGENTS.md as required? I ran into that problem yesterday when I was creating an extension that can jump to another project. I couldn't find a way to do it.
