Summary

• Issue #149: Grid columns no longer wrap the last column into empty right-side space on open or after right-panel/splitter resize. Column math re-applies on viewport resize, reserves scrollbar width only when the bar is not already consuming space, and re-runs after content preload.
• Sequential selection: Shift+click selects contiguous images in list order from the selection anchor through the clicked thumbnail (not a rectangular column block in IconMode).
• Release 0.4.2 (patch): CHANGELOG, USER_GUIDE, DESIGN updates.

Test plan

• Open a directory with enough images for multiple grid rows and a vertical scrollbar — last column fills available width without a large empty strip on the right
• Resize the window and drag the right-panel splitter — columns reflow correctly without needing a zoom nudge
• Change thumbnail size up/down — layout remains correct (existing path)
• Click image A, Shift+click image B several rows away — selection includes every image between A and B in grid order, not only a rectangular block of columns
• Ctrl+click to multi-select, then Ctrl+Shift+click — range is added without clearing the rest of the selection
• pytest tests/test_grid_selection_filter.py tests/test_pr7_shell.py tests/test_thumbnail_generator.py tests/test_grid_input_filters.py

fix(ui): stabilize grid columns on open and splitter resize (#149) ... 45185865b5

Re-apply justified column math when the grid viewport resizes (including
splitter/right-panel changes that skip MainWindow.resizeEvent), reserve
scrollbar extent only when the bar is not already consuming viewport
space, and coalesce layout passes so open/load no longer wraps the last
column into empty right-side space.

fix(ui): sequential model-order Shift selection in thumbnail grid ... c8ecc045a8

IconMode Shift+click used a visual rectangle (square block of columns).
Select contiguous model rows from the selection anchor through the
clicked item instead, and avoid setCurrentIndex wiping multi-select.

test: cover grid column fit and sequential Shift selection ... 631625efb4

Regression tests for issue #149 column layout after right-panel apply
and content load, plus Shift/Ctrl+Shift sequential range selection.

docs: PR-prep for 0.4.2 grid columns and sequential selection (issue #149) ... 06024ab7b0

Bump VERSION to 0.4.2, document the column-layout and Shift-range selection
fixes in CHANGELOG and the bundled user guide, and note the grid viewport
re-layout and sequential selection behavior in DESIGN.md.
