AlphaDocs 0.1.5

This maintenance update fixes issues found in another native interaction QA pass:

• Fast horizontal scrollbar drags keep the correct pointer owner, including the corner where the two bars meet.
• Fast mouse drags select text correctly even when the gesture arrives in one frame.
• Saving and exporting keep your reading position. Unhandled Escape presses no longer jump to the caret.
• Editor panels no longer cover window resize edges.
• Invalid custom colours cannot pin an older preview value; duplicate/full palettes explain why pinning is disabled.
• Signature drawing stops cleanly when the pointer or window focus is lost.
• The empty homepage accurately reflects the Autosave preference.
• Emoji in body text export with the bundled fallback font, including joined and skin-tone sequences.
• Closely spaced checklist items have distinct click regions and properly sized marks on screen and in PDF.
• Missing or invalid files show an opening error without replacing the current document.

Full UI-frame regression coverage includes both themes, 100%/200% zoom, 960–1920-pixel layouts, selection preservation and undo. Native Windows interaction checks and automated platform checks are distinct from physical Mac/Linux device testing.
