Cmd+W closes the window on macOS, so the Command half of the pair is left
alone; this is the one shortcut that is not bound on both modifiers.

Joins the Command/Control shortcut pairs, so the chord works the same on
either platform, and the View menu entry now shows it.

Tree / Palette hides the left column so the wiresheet has the whole window.
ttk has no hide flag for a pane, so the column is dropped from the paned
window and re-inserted at the front, which is why the configured width is
re-applied afterwards.
Back and Forward walk the sheets opened this session, with two arrow buttons
in a new toolbar on the same commands. History entries hold the element whose
children are painted rather than a tree item id: rebuilding the tree hands out
fresh ids, while the elements themselves survive. Recording runs from the tree
selection handler, the one route every sheet opening takes, and is suppressed
while a walk drives that selection so it cannot rewrite its own trail. Opening
a different file retires the history; a delete or an undo drops only the
entries whose element has left the document, keeping the position on screen.
open_file builds the tree inline instead of going through
refresh_treeview_from_dom, so it never raised the tree-filled callback and the
history had no way to see a new file. It and reset_to_startup_state now fire
it, which also gets the tree column fitted on load rather than on the first
resize.

A kit with no manifest under the Sedona home folder called sys.exit(1),
tearing down the whole app over one unopenable file.
schema now raises MissingManifestError instead, collecting every
unresolved kit first so one dialog names them all rather than the user
fixing them one reopen at a time. describe_missing_manifests builds the
body, pointing at the configured Sedona home and at Preferences.
open_file catches it, reports it, and calls the new
reset_to_startup_state to return to the just-launched state: no file,
empty tree, empty sheet, cleared registries and undo stack. The generic
except now resets too, since a half-parsed file previously left
current_file_path and a stale root behind.
Placing a palette component hits the same loader, where a full reset
would be too destructive: it rolls back the <kit> entry it just added,
rebuilds the previous registry, and abandons only that placement.
schema no longer imports sys or tkinter, so it reports nothing itself
and stays testable without a display. base_window_title moves to
app_state so the reset can restore the title without duplicating it.
README: document the new behaviour, drop the fixed gap, and correct the
stale "no undo, no keyboard shortcuts for save" claim.
