Add user config to use hunk mode by default when entering staging view (
#4685)
- **PR Description**
As of #4684, hunk mode has become so useful that I prefer it over line
mode now. This PR adds a config that lets you use hunk mode by default
in the staging view.
I'm not enabling this by default yet, although I do think it's the more
useful mode for most people. The biggest issue that I still have with
this is that _if_ you need to switch to line mode for some reason, then
it's very non-obvious how to do that. New users might not find out at
all, and think that lazygit doesn't allow staging individual lines.

Fix assigning custom key to pullFiles command in the Commits panel (#…
…4617)
- **PR Description**
Improve the dispatching of key bindings so that remapping "pullFiles" to
a different key works correctly in the Commits panel.
Fixes #4614.

Fix lazygit's UI becoming unresponsive when a background fetch asks f…
…or a passphrase (#4586)
Fix a regression introduced with #4525.
This fixes the problem that background fetching makes lazygit hang when
the fetch request needs to prompt for a passphrase. For Mac users who
use the keychain to store their ssh passphrases, this can happen when
lazygit is running while the machine goes to sleep, because macOS looks
the keychain in that case.

Fix crash when clicking in the status view (#4567)
- **PR Description**
The status view is not supposed to be focusable right now. (This might
change soon, but for now it isn't.) Pressing '0' on it does nothing.
However, clicking on it would still focus it, because the click handler
in MainViewController assumed that when the clicked view doesn't have
the focus, then its "other" view must have, and we just want to toggle
the focus between the two (like when pressing tab). It didn't take the
possibility into account that the current side panel isn't focusable at
all; if it was, then its SwitchToFocusedMainViewController would have
handled the click.
To fix this, check if the "other" view has the focus before handling the
click, and do nothing otherwise.
This also fixes clicking in the main views of the Worktrees or
Submodules tabs, or any other tabs whose main views are not focusable.
Fixes #4566.

Reduce memory consumption of graph (pipe sets) (#4498)
- **PR Description**
As a followup to #2533, reduce the memory consumption some more by
optimizing the storage of the pipe sets used for the commit graph.
Some coarse measurements (taken by opening the respective repo, typing
`4 >`, and waiting for all commits to be loaded, and then reading the
Memory column in Activity Monitor):
|               | master  | this PR |
| ------------- | ------- | ------- |
| git           | 2.5 GB  | 1.0 GB  |
| our work repo | 2.3 GB  | 1.3 GB  |
| linux kernel  | 94.8 GB | 38.0 GB |
It's still not really usable for the linux kernel, but for all other
repos that I come across in my daily use of lazygit, it works quite well
now.
