leonarski_fandClaude Opus 5 501ce1ba3d Viewer: rate-limit hover feedback to ~15 Hz
The status bar, the resolution readout and the magnifier were all regenerated
on every single mouse motion event. Each regeneration repaints, and on a remote
X session a repaint uploads the whole window regardless of how little changed,
so the pointer merely crossing the image saturates the link: measured with a
counting relay in front of the X server, 50 motions over the image cost 273 MB,
and a build with the hover work removed cost 18 KB.

Rate-limit it. Two details matter:

- The limit is applied inline, not from a timer. Running the update inside the
  mouse event keeps its damage in the same repaint as anything else that event
  triggers (a pan). A first attempt deferred the work to a timer instead, which
  split one repaint into two and made panning measurably worse.
- The catch-up that reports the final position is debounced, not queued per
  skipped motion, so it fires once after the pointer stops rather than
  repeatedly mid-gesture.

mouseHover() now takes the scene position and modifiers instead of the event,
which also removes the identical mapToScene() from all four implementations.

Hover traffic over 3 repeats: 173 MB mean -> 140 MB, and the run-to-run spread
drops from +-14% to +-2%. The harness tops out near 30 motions/s, barely above
the 15 Hz limit; a real mouse reports far faster, where the cap does more.

This is an UNSTABLE release. It includes many experimental features, as well as many AI generated fixes. We recommend using rc.152 for production use.

* jfjoch_broker: Add EXPERIMENTAL pixelrefine mode for image processing
* jfjoch_broker: Allow to load user mask from 8-bit and 16-bit TIFF files
* jfjoch_broker: Add ROI calculation in non-FPGA workflow
* jfjoch_broker: Fixes to TCP image pusher
* jfjoch_broker: Remove NUMA bindings
* jfjoch_broker: Improvements to indexing
* jfjoch_broker: For PSI EIGER, trimming energies are taken from the detector configuration (now compulsory) instead of hardcoded values
* jfjoch_writer: Save ROI definitions and the per-pixel ROI bitmap in the master file; azimuthal ROIs support phi (angular) sectors
* jfjoch_viewer: Major redesign with dockable panels and saved layouts, plus on-canvas creation/move/resize of box, circle and azimuthal ROIs
* jfjoch_viewer: Run jfjoch_process reprocessing jobs from inside the GUI and overlay per-run results

This is an UNSTABLE release.

jfjoch_writer: Fix and improve the way grid scan geometry is saved (non-NXmx extension makes it way easier)
jfjoch_viewer: Display grid scan results in 2D (work in progress)
jfjoch_viewer: Improve auto-scaling on start of images (work in progress)
jfjoch_viewer: Add B-factor and resolution estimate to the dataset info plots
