* Dataset-info plot hover shows a horizontal crosshair alongside the existing
vertical one, so a run of hovers reads as a level or a drift at a glance.
* `A` applies auto-contrast once instead of switching on persistent Auto mode
(a new `oneShotAutoForeground()`, distinct from the toolbar's Auto toggle);
pressing it a second time on the same image switches Auto on for good, and
pressing it while Auto is already on leaves it on. The value itself comes
from one `AutoForegroundValue()` shared with the continuous Auto path.
* `Home`/`End`/`Page Up`/`Page Down` navigate the dataset (first/last image,
one image forward/back); claimed in the diffraction view's keyPressEvent
before QGraphicsView's default handling, which otherwise eats them to
scroll the viewport.
* Alt+wheel dataset navigation is removed - some window managers already
took it before the app ever saw it, per the caveat that used to sit next
to its entry in the shortcuts list.
* The image strip dock and its dedicated thumbnail-rendering machinery in
the reading worker (SetThumbnail*, RenderThumbnail_i) are removed; it cost
a lot and nothing else used any of it.
* Toolbar text: "Colour" -> "Color".
* Color map, Auto and HDR mode now persist across sessions, the same way the
window layout already does.
* The Inspector's "Dataset:" path wraps at '/' (a zero-width space after
each one) instead of being cut off when it doesn't fit one line.
* LoadFile no longer reopens an already-open file - it forwards straight to
LoadImage instead - which was the likely cause of a D-Bus client's per-image
navigation lagging behind the same navigation done via the grid-scan hover.
* New file-manager dock (left, tabbed with Settings via tabifyDockWidget):
a directory tree filtered to *_master.h5/*_process.h5, rooted at
JUNGFRAUJOCH_DATA_ROOT if set, else the last-browsed root, else the home
directory. Most beamline users care about opening images, not
reprocessing settings, so it's the tab raised by default. Its filter box
narrows files only - a directory always passes - because filtering the
directories too hid the matching files under any directory whose own name
did not match, and hid the root's ancestors, which left the tree with no
valid root index until the root was set again by hand.
