multi-console: reconsider approach to console history (separate histories per session)

but I think any multiconsole enabled console will see the same behavior.

Interpreter details:

Any Python interpreter.

Describe the issue:

No history is maintained (or maybe repopulated?) when Positron is shut down. IPython terminals have memory of historical commands, and I was expecting to be able to arrow up ⬆ into previously run commands. If I open another REPL via ipython in the Terminal pane, I'm able to see the commands I ran.

Steps to reproduce the issue:

1. in a console, run foo = 'bar'
2. shut down Positron
3. reopen Positron
4. in running console, press up arrow (or run %hist) and see nothing. I exp

Expected or desired behavior:

I expected to see the last run cell, foo='bar'

Were there any error messages in the UI, Output panel, or Developer Tools console?

None

Start by reproducing the shutdown and restart sequence with a Python console, then inspect how console history and sessions are handled. Done means previously entered commands remain available after reopening Positron and histories are separated appropriately for each console session.
