lazygit 0.66.0 አውርድ

This is by far the biggest release since I took over maintainership from Jesse, and some of the changes deserve a bit more explanation than usual.
- Staging hunks is now done directly from the main view.
There used to be a separate staging panel that you had to enter if you wanted to stage individual diff hunks; it was limited to one file at a time, and showed the raw git diff rather than the configured diff renderer. This is gone; the main view now has a selection when you focus it, and you can act on the selected hunk or line directly there:
- press space to stage a hunk or range of lines
- navigate to the next/previous hunk with <right>/<left>, or the next/previous file with n/N
- press e to jump to the editor on the selected line
- press d to discard a hunk.
Many other enhancements were added to this new interactive diff view:
- alt-click a line to jump to that line in the diff view (this works even when a popup panel is showing above it, e.g. the commit message editor)
- press <ctrl-g> to see a menu with all the files in the diff, to quickly jump to one of them
- the files in the diffstat below the commit message are clickable hyperlinks that take you to the clicked file in the diff, like the <ctrl-g> menu does
- when changing the diff context using {/}, or when toggling the "ignore whitespace" option (<ctrl-w), the scroll position is preserved
If you use a custom diff renderer, all of this works with the renderer's output, as long as it supports the new OSC protocol that was introduced for this. Delta and Diff-so-fancy already do, so if you use one of these, be sure to update them to the latest version. There is support for difftastic too, but it hasn't been accepted upstream, so you'll have to build it yourself from this PR. If you use any other diff renderer, please file an issue so that we can add support for it.
- Better support for stacked branches.
- You can now push or force-push all branches of a stack at once, simply by pushing the topmost one. Lazygit will ask you if you want to push the others as well.
- Same for pulling: if a branch stack was rebased by someone else, you can pull the topmost branch and lazygit will ask you if you want to pull the other branches in the stack too, without checking them out.
- Branches of a stack are now listed in order in the branches panel. When rebasing a stack it is common for all branch tips to get the same committer date, in which case git sorts them alphabetically, which is confusing. We now have extra logic to preserve the stack order in this case.
- Unrelated to stacks (but common to show up in that case): when a branch diverges from its upstream (you see ↓3↑5) it was impossible to tell whether that was because you rebased or rewrote the branch, in which case you want to force push, or because someone else rebased the branch, in which case you want to pull it. Lazygit can now distinguish these cases, and will show the ↓3↑5 in a dimmer yellow in the latter case. What's more, in this latter case you can "pull" the branch without checking it out by pressing f, like you already could for branches showing ↓7.
- Dark and light themes.
Lazygit now determines whether your terminal has a dark or light background, and can use different color themes for each; it can also switch between the two dynamically if your terminal does. You can also pass this information on to your diff renderer if you use one that needs it, by using the new {{colorScheme}} template variable in the renderer command.
- Better rendering of the commit graph.
Since the commit graph uses box drawing characters it could only be an approximation; some graph topologies can't be rendered faithfully this way. We now make use of branch drawing characters if the terminal supports them, which solves this problem and also looks better; see #6077 for details.
