Stefan Haller 88dae2f2c6 Collapse the focused-main-view handler channels into one
Each command a side panel handles in the focused main view needed its own
delegation channel: a HasKeybindings getter, an IBaseContext Add method, a
BaseContext field + getter, a baseController nil default, and an attach.go
registration — roughly five touch points per command. With three commands
(click, stage, toggle-patch) that was already a lot of boilerplate, and it
doesn't scale to the discard / copy commands coming next.

Replace the three channels with one: a side panel exposes a single
FocusedMainViewActions interface via GetFocusedMainViewActions (nil when its
diff offers no actions), and the controllers implement that interface
directly. The stage and toggle-patch handlers, already unified to a plain
error return, become one PrimaryAction method whose meaning is the panel's
business (stage for the files panel, patch toggle for the commit panels);
the click handler becomes OnClick. MainViewController is now a thin
dispatcher: fetch the actions from the panel beneath, call the method.
Adding a command is now one interface method, an implementation in the two
or three controllers, and a keybinding — no plumbing.

The toggle-patch channel did double duty as the "this panel builds a custom
patch" signal for the inclusion gutter (shown only beneath a patch-building
panel, not the staging files panel). Collapsing the channels removes that
proxy, so make the classification explicit on DiffMainViewContext, whose
marker method now returns a DiffMainViewType (none / staging / patch-building)
instead of being a bare marker. The gutter shows only beneath a panel whose
type is patch-building (commit files, local commits, sub-commits, stash).

Behavior-preserving.
