Windows 11's major version number is actually 10.x.x, which can be confusing
if you don't know about this quirk. `OS.get_version_alias()` avoids this
by displaying the "branding" version number and the build number as a suffix,
so that individual updates can still be distinguished from each other.
On macOS, `OS.get_version_alias()` returns the version number prepended
with the version name (e.g. Sequoia for macOS 15).
On other operating systems, this returns the same value as `OS.get_version()`.
We now cache the Node*<>TreeItem* mapping in the SceneTreeEditor. This
allows us to make targeted updates to the Tree used to display the scene
tree in the editor.
Previously on almost all changes to the scene tree the editor would
rebuild the entire widget, causing a large number of deallocations an
allocations. We now carefully manipulate the Tree widget in-situ saving
a large number of these allocations.
In order to know what Nodes need to be updated we add a
editor_state_changed signal to Node, this is a TOOLS_ENABLED,
editor-only signal fired when changes to Node happen that are relevant
to editor state.
We also now make sure that when nodes are moved/renamed we don't check
expensive properties that cannot contain NodePaths. This saves a lot of
time when SceneTreeDock renames a node in a scene with a lot of
MeshInstances. This makes renaming nodes go from ~27 seconds to ~2
seconds on large scenes.
SceneTreeEditor instances will now also not do all of the potentially
expensive update work if they are invisible. This behavior is turned off
by default so it won't affect existing users. This change allows the
editor to only update SceneTreeEditors that actually in view. In
practice this means that for most changes instead of updating 6
SceneTreeEditors we only update 1 instantly, and the others only when
they become visible.
There is definitely more that could be done, but this is already a
massive improvement. In complex scenes we see an improvement of 10x,
things that used to take ~30 seconds now only take 2.

I want to thank KoBeWi, TokisanGames, a-johnston, aniel080400 for
their tireless testing. And AeioMuch for their testing and providing a
fix for the hover issue.
3205a92ad8 was a major commit which removed `PoolVector`, and replaced
most references to `PoolVector` with `Vector` instead. In most cases,
this was appropriate, given that `PoolVector` was being replaced with
`Vector`, as an effective generalist in 64-bit address space layouts.
However, vector.h itself was left with an artifact advising the reader
to use `Vector` instead of `Vector` for large arrays. While this led
to a fascinating deep dive, and hopefully improved some of the
documentation along the way, it's probably best to clean this up for
the next person.
