Subject: [PATCH] Mirror the Build view into the file Explorer
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds `fallout.buildExplorer`, a second home for the build targets docked in
the Explorer, collapsed by default so it costs nothing until opened.

It is the *same* provider instance, not a second one — so the graph is loaded
once and a single refresh() updates both views. Registering a second instance
would double the file watching and let the two drift apart.

The view/title and view/item/context when-clauses now match either view, which
is why the run/go-to inline actions work identically in both.

Closes #10
