Summary

Adds a 1:1 button beside Fit in the image viewer's right-column controls. It resets the view transform to identity (one image pixel per screen pixel) and switches scrollbars to as-needed so an oversized image can be panned.
Bumps VERSION 0.7.0 -> 0.7.1 (compiled-input change) and adds a CHANGELOG entry.
Documents the new button in resources/help/USER_GUIDE.md.

Threading notes: purely main-thread QGraphicsView/QPushButton work, no worker involved.

Closes #158.

Manual headless smoke test with a real 2000x1200 image: Fit scaled to 0.321x, clicking 1:1 snapped the transform to exactly 1.0 and enabled scrollbars (screenshot reviewed)

feat(viewer): add 1:1 actual-size zoom button (issue #158 ) 442869c06d

Adds an "Actual Size" button beside Fit in the image viewer's right
panel. Resets the view transform to identity (one image pixel per
screen pixel) instead of scaling to the viewport, and switches
scrollbars to as-needed so oversized images can be panned.

Threading notes: purely main-thread QGraphicsView/QPushButton work,
no worker involved.

Document the viewer's new 1:1 actual-size button in the bundled user
guide, add a 0.7.1 CHANGELOG entry, and bump VERSION to the next
release (0.7.0 -> 0.7.1; compiled-inputs-changed.sh confirms src/
changed on this branch).
