Proofreading a dense section (for example auto-segmentation output) often means working on one or a few traces while many others crowd the field. An invert-selection action lets the user pick out a working set quickly by selecting the few traces to exclude and then flipping the selection. Invert selection (Ctrl+Shift+I) flips which traces are selected on the current section. Hidden and group-hidden traces are skipped unless show-all traces (A) is active, and locked objects are never selected, matching the existing selection paths. Selected ztrace points and flags are left untouched. Like the other selection operations it is a view convenience and is not itself undoable. The action is wired into the field trace context menu next to Select all and Deselect, registered in the default shortcuts, and listed in the keyboard-shortcuts help dialog. Refs #71
Proofreading a large auto-seg ROI is sluggish because every object stays live. An object spans many sections, so isolating a working set has to persist as the user pages through the volume, not just on one section. Object list: * Invert selection flips which objects are selected in the list. Object rows are freely selectable, so nothing is excluded; with no active filter this inverts against every object in the series. It lives in a new "Selection" menu and is prepended to the object right-click menu (it is a table selection operation, so it belongs with the list rather than in the shared field object menu). * Hide unselected objects hides every other object throughout the whole series via the existing series-wide Series.hideObjects path, so the isolation persists across sections. It is undoable series-wide (the same machinery as the existing object Hide), and Show all objects is the clear restore. Objects in the complement are hidden regardless of lock state, since locking guards edits and quantification rather than visibility. An empty selection is a no-op, so the series is never fully blanked. Hide unselected objects and Show all objects are field methods, so they are also reachable from the object right-click menu and act on the object(s) owning the field's selected traces. Refs #71

Adds Invert selection to the field (Ctrl+Shift+I) and the object list, and Hide unselected objects / Show all objects to isolate a working set across the whole series. Isolation uses the existing series-wide hide path, so a single undo restores every section.
Closes #71.
