The next commits move refresh workers to read UI-thread-owned state (the
model, contexts, selection) on the UI thread rather than off it. Two
primitives support that:
- OnUIThreadAndWait runs a function on the main event loop and blocks the
caller until it has run, so a worker can read that state without racing.
OnUIThreadAndWaitBackground is the same for background routines, whose
work must not count towards the program being busy.
- IsUIThread reports whether the caller is on the main event loop, for a
debug-only assertion that a refresh was issued from the thread it claims.
It records the main loop's goroutine id in MainLoop and compares via
goid, so it's promoted from an indirect to a direct dependency.
goid is used only by that debug assertion, never to drive production
control flow.

The repo-switch busy query must not count view-buffer content rendering:
those tasks paint a view rather than drive a git operation, so leaving
one running across a switch is harmless (the switch's own refresh
re-renders). More importantly, they fire on nearly every focus/selection
change — including the context activation that runs right before a
menu/prompt confirmation handler (e.g. confirming worktree creation).
A synchronous busy check in such a handler would otherwise see that
render and make the very switch the handler is about to request refuse
itself.
Route ViewBufferManager's tasks through a new gocui NewBackgroundTask so
they're tracked for idle detection but excluded from the busy query. The
task "background" flag now covers two kinds of non-blocking work: the
background routines (and their refreshes) tagged earlier, and view
rendering.

Repo-switch safety needs to answer, synchronously on the UI thread,
"is any foreground work in flight right now?" so it can refuse a switch
that would run against a repo about to be swapped out. gocui already
tracks a task per OnWorker/Update for the test idle-listener; extend
that.
Tasks gain a background flag: background tasks (the ongoing routines
like auto-fetch, and the refreshes they trigger) don't count towards
busy, because their model writes are already guarded against a
concurrent switch by the repo generation. Add OnWorkerBackground,
UpdateBackground and UpdateContentOnlyBackground (plus the gui-layer
OnUIThreadBackground / OnUIThreadContentOnlyBackground / OnWorkerBackground
on IGuiCommon) so the few background call sites can opt in without
touching the hundreds of foreground callers.
TaskManager.hasBusyForegroundTaskExcept answers the query; Gui.Busy()
wraps it, excluding the event currently being processed (recorded as
currentTask) so a handler asking the question doesn't count itself.
Nothing gates on Busy() yet; this is the mechanism only.

Update spawned a goroutine per call that then sent on the user-events
channel, so multiple Update calls from the same goroutine could be
reordered by the scheduler — the doc comment even admitted "the order in
which the user events will be handled is not guaranteed." That
non-determinism is a latent source of flaky rendering: code that queues a
model update and then a render in source order could see them run in the
opposite order.
Send on the channel directly instead, so same-goroutine calls arrive in
source order. The send is non-blocking and panics on a full channel
rather than blocking (a blocked send from the UI goroutine would deadlock
against itself) or silently reordering; the buffer is sized generously so
this is unreachable in normal use. UpdateAsync is now identical to Update
and unused, so it's removed along with the shared updateAsyncAux helper.
Lazygit reloads changed config files when its terminal window regains
focus, but the test harness had no way to simulate that focus event, so
the live config-reload path was untestable. Add a focus event to the
replayed-events queue and expose it through the GuiDriver as FocusIn.

The cells of a source line will soon need to carry metadata about how
the line was terminated (newline vs filled to edge via \x1b[K). Move
to a struct so there's somewhere to put it; this commit only renames
[][]cell to []line{cells: ...} with no behavior change.

Until now every keybinding config field was a plain string. That meant a user
couldn't ask for two keys to invoke a command — the config silently accepted
only one form.
Convert every string-typed field across all 13 KeybindingXxxConfig structs to
Keybinding so the union type extends to every command. Defaults wrap their
single-key value in Keybinding{...} so the generated Config.md still renders one
scalar key per binding.
The alt fields keep their separate Binding registrations for now: this commit
does not yet introduce the merge mechanism that folds them into the main field —
that comes in a follow-up. Consumers previously calling opts.GetKeys on a string
field now call opts.GetKeys on the Keybinding, or take .String() / Keys[0] where
a single value is needed.
Adds a Keybinding.String helper for rendering, schema-generator work that
inlines the Keybinding union into each consuming property, and a unit test
covering the user-facing scalar/sequence YAML forms for quit.
This prevents views from drawing over higher z-order views.
Currently this is not an issue in practice, because we use
ForceFlushViewsContentOnly only for the bottom line status spinner, and there
are never views on top of it. However, later in the branch we will use the
mechanism to redraw the inline spinners in panels (e.g. the "Pushing..." status
next to a branch name), and there could be a popup on top of it.

Modifiers were moved into Key in 22169e22f, but the separate Modifier field
on types.Binding and gocui.keybinding was left behind. The keypress matcher
already compares modifiers via Key.Equals, so the old field is never read on
the dispatch path; it just got passed through SetKeybinding and stored.
Drop it from gocui.keybinding, types.Binding, and the SetKeybinding /
DeleteKeybinding signatures, and remove every now-redundant Modifier:
gocui.ModNone struct field. Mouse bindings keep their own Modifier (on
ViewMouseBinding) since that path still consults it.
I noticed that it compares key.keyName and key.str separately instead of calling
key.Equals, but instead of deciding whether that's a problem, just delete the
function when nobody needs it.
This changes not only how we store modifiers (inside of Key instead of passing
it separately), but also how we parse keybinding strings: it supports all
combinations of modifiers now (if the terminal supports it, that is).
This bundles the keyName and a rune, so that we don't have to pass these around
separately everywhere. This should make it easier to swap out the rune for a
string when we upgrade to tcell v3.
I copied all files except dot files (.github and .gitignore), the _examples
folder, and go.mod/go.sum.
At some point we may want to copy the files back to the gocui repo when other
clients (e.g. lazydocker) want to use the newer versions of them.
