sticky explorer and session

- [x] windows and session
There are a few issue with persisent when closing buffers.
I.E when sticky explorer (snacks.lua > E) is open and a close window/tab is invoked, the explorer gets closed
(This is caused by closing the window instead of the buffer)

- [ ] explorer navigation with i key using "confim_folder" instead of Enter
Its not working as is should (found it snacks.lua)
- [ ] If using e when side explorer is open, it should move focus to it
- [ ] find another key map for select all (currently ctrl+a)
- [ ] move from input to picker seamlessly with Esc
