Moves the wlayout package contents to wcore to prevent import cycles.
Moves the layout calls to other wcore functions instead of being handled
by the services. Removes redundant CreateTab in EnsureInitialData and
adds a isInitialLaunch flag to the CreateTab and CreateWorkspace
functions to ensure that the initial tab is pinned and does not have the
initial tab layout (since the starter layout gets applied later)
Adds a new app menu for creating a new workspace or switching to an
existing one. This required adding a new WPS event any time a workspace
gets updated, since the Electron app menus are static.
This also fixes a bug where closing a workspace could delete it if it
didn't have both a pinned and an unpinned tab.
This functions very similarly to VSCode's pinned tab feature. To pin a
tab, you can right-click on it and select "Pin tab" from the context
menu. Once pinned, a tab will be fixed to the left-most edge of the tab
bar, in order of pinning. Pinned tabs can be dragged around like any
others. If you drag an unpinned tab into the pinned tabs section (any
index less than the highest-index pinned tab), it will be pinned. If you
drag a pinned tab out of the pinned tab section, it will be unpinned.
Pinned tabs' close button is replaced with a persistent pin button,
which can be clicked to unpin them. This adds an extra barrier to
accidentally closing a pinned tab. They can still be closed from the
context menu.
Fixes issue where closing the last tab in the last window would cause
app to show a blank window the next time it opens. Instead, we should
dispose of the window so that it can be created from scratch the next
time the app launches.
Also fixes a potential DB resource leak from dead windows cluttering up
the DB
Adds a flag to the insert layout action to explicitly set the focus of a
newly inserted node. This also adds a flag in the starter layout to
focus on the terminal block.
