* Remove unnecessary WindowContext and ViewContext '_ lifetimes
* Removed some cases where WindowContext has a different name than `cx`.

- N/A
Closes https://github.com/zed-industries/zed/issues/21652
* prevents zooming out the panel when any terminal pane is closed
* forces focus on new terminal panes, to prevent the workspace from
getting odd pane events in the background
Release Notes:
- (Preview only) Fixed zoomed terminal pane issues on split
Fixes part of issue #7808
> This venv should be the one we automatically activate when opening new
terminals, if the detect_venv setting is on.
Release Notes:
- Selected Python toolchains (virtual environments) are now automatically activated in new terminals.

Closes https://github.com/zed-industries/zed/issues/4351

Applies the same splitting mechanism, as Zed's central pane has, to the
terminal panel.
Similar navigation, splitting and (de)serialization capabilities are
supported.
Notable caveats:
* zooming keeps the terminal splits' ratio, rather expanding the
terminal pane
* on macOs, central panel is split with `cmd-k up/down/etc.` but `cmd-k`
is a "standard" terminal clearing keybinding on macOS, so terminal panel
splitting is done via `ctrl-k up/down/etc.`
* task terminals are "split" into regular terminals, and also not
persisted (same as currently in the terminal)
Seems ok for the initial version, we can revisit and polish things
later.
Release Notes:
- Added the ability to split the terminal panel
This adds the ability for Zed to restore unsaved buffers on restart. The
user is no longer prompted to save/discard/cancel when trying to close a
Zed window with dirty buffers in it. Instead those dirty buffers are
stored and restored on restart.
It does this by saving the contents of dirty buffers to the internal
SQLite database in which Zed stores other data too. On restart, if there
are dirty buffers in the database, they are restored.
On certain events (buffer changed, file saved, ...) Zed will serialize
these buffers, throttled to a 100ms, so that we don't overload the
machine by saving on every keystroke. When Zed quits, it waits until all
the buffers are serialized.
### Current limitations
- It does not persist undo-history (right now we don't persist/restore
undo-history regardless of dirty buffers or not)
- It does not restore buffers in windows without projects/worktrees.
Example: if you open a new window with `cmd-shift-n` and type something
in a buffer, this will _not_ be stored and you will be asked whether to
save/discard on quit. In the future, we want to fix this by also
restoring windows without projects/worktrees.

### Related tickets
I'm unsure about closing them, without also fixing the 2nd limitation:
restoring of worktree-less windows. So let's wait until that.

### Note on performance
- Serializing editing buffer (asynchronously on background thread) with
500k lines takes ~200ms on M3 Max. That's an extreme case and that
performance seems acceptable.
Release Notes:
- Added automatic restoring of unsaved buffers. Zed can now be closed
even if there are unsaved changes in buffers. One current limitation is
that this only works when having projects open, not single files or
empty windows with unsaved buffers. The feature can be turned off by
setting `{"session": {"restore_unsaved_buffers": false}}`.
