Entering tmux with live inshellisense session breaks suggestions

[whiskeyo]

Describe the bug With inshellisense session enabled, entering tmux "disables" suggestions completely. Also, after first turning on tmux and then running is, everything works fine.

To Reproduce Steps to reproduce the behavior:

1. Enable inshellisense session by is -s bash
2. Check if inshellisense is enabled by is -c (session is live)
3. Input any command, e.g. git - suggestions appear
4. Turn on tmux (my version is 3.3a), check if inshellisense is still enabled (it shows it is live)
5. Input any command, e.g. git - no suggestions appear

Expected behavior As long as is -c return that session is live, I expect the session to be fully functional.

Environment

• OS: Windows 11, running Debian in WSL2
• Output of is --version: 0.0.1-rc.9, running on latest commit from main
• Nodejs Version: v18.19.0
• Shell: bash + oh-my-bash
• Shell Version: 5.2.15(1)-release (x86_64-pc-linux-gnu)

Additional context I got the reproduction and uploaded it to YouTube: https://www.youtube.com/watch?v=-s5pHjnGLtI

@whiskeyo, since tmux is multiplexing multiple shell sessions, you'd want to start a new inshellisense session per view, rather than starting inshellisense globally. I don't think it's feasible to try to track multiple possible prompt points from one inshellisense session.
