Version: [4732] Geochemistry Plotting Tools 0.0.5

Declared explicit numpy/matplotlib version ranges in requirements.txt,
harmonised with the GEOL-QMAPS and Stereoplot plugins, so installing
all three on the same QGIS Python environment converges on one
mutually compatible dependency set.
  * Fixed a bug where a missing matplotlib installation crashed at
import time instead of degrading gracefully.
  * Fixed a Qt6/QGIS4 compatibility bug affecting QAction, which moved
from QtWidgets to QtGui in Qt6.
  * Declared Qt6/QGIS4 support in metadata.txt, now that Qt6
compatibility has been verified.
  * Add Geochemical Differentiation of Sedimentary Rocks ternary
diagram (Hasterok et al. 2018, after Mason 1966), with a
first-screening check for required oxide fields and a
below-detection-limit (negative value) handling option
  * Add category mean ± 2σ statistics overlay (all plot tabs), toggled
live from the interactive style panel: shows each category's mean ± 2σ
with individual samples faded behind it, or replaced by a
semi-transparent contour-less envelope, with adjustable background
opacity and error bar/marker thickness; the mean marker follows bubble
sizing when active and stays in sync with the category's colour/marker
  * Add per-category drawing (z-stack) order control to the
interactive style panel
  * Add hollow/full symbol fill option (white fill, coloured outline)
to the interactive style panel
  * Add interactive per-category style panel (colour, marker, size,
transparency) with save/load/reset/delete templates, replacing the old
style JSON file
  * Add "no category" option to plot all points with a single symbol
  * Add bubble plots: scale symbol size by a chosen field (linear,
log10 or exponential scaling), available for every plot type
  * Add Filter Layer to Selected / Clear Filter buttons to turn a plot
selection into a QGIS layer filter
  * Fix Ti vs Zr (Pearce & Cann 1973) diagram and add automatic
ppm/ppb/wt%/oxide unit conversion across all plots
  * Recognise many more elements and oxides in Custom XY plots
  * Add Data Preprocessing sub-tab to Custom XY for
below-detection-limit (negative value) handling, with substitution
options and a review/histogram tool
  * Add plot-type dropdown to the Minerals tab, ready for future
classification schemes
  * Improve point label readability (white background) and stacking
order (always drawn above points)
  * Various dock panel usability fixes: horizontal scrolling, tabs
resize to content, tighter control alignment
