Support WSL terminals

[zivni]

Description of the new feature

When opening the agent from WSL Ubuntu terminal, the agent is not aware that it is in an Ubuntu terminal and gives results of a PowerShell. It also unable to insert the commands into the WSL terminal.

For example I asked " show hidden folders", the result was " Run: Get-ChildItem -Force -Directory | Where-Object { $_.Attributes -match 'Hidden' }".

Choosing to insert the command to the terminal resulted with "Choice 1 failed: failed to send input to pane activeTarget: wtcli failed: [wtcli] Connection failed: 0x80010105 The
server threw an exception."

On a similar note I was wondering what this would do when connecting to remote hosts over ssh. Might warrant it's own issue to track separately.

For the feature itself it can understand that the context is from wsl:

But the problem is the broken part: We internally use 'wtcli' to interact with terminal to get shell info, and behind the scene is the broken com thing

For detail:

We have verified the com work on latest 24H2

Does it support connecting to ACP in WSL, such as OpenCode or CodeX?

@zivni we will investigate this further. Please attach logs so we can investigate further. See here: https://github.com/microsoft/intelligent-terminal#collecting-logs

Currently, the agent pane should understand wsl/bash context, be able to insert and run commands in that shell as well. For example, in Ubuntu, running the same "show hidden folders":
