Bbannotate/dev v1.0.9

[seba2390]

Added

• Adjustable draw crosshair controls in canvas toolbar (arm length and stroke width)
• Persistent crosshair preferences via localStorage

Changed

• Refined the canvas top toolbar into compact titled groups (Controls, Zoom, Label, Box, Cursor) with consistent control heights
• Updated Controls to always-visible compact tool buttons (Select, Draw, Pan) under the title
• Moved zoom actions into a compact expandable panel under Zoom to reduce toolbar width
• Replaced always-visible cursor sliders with compact expandable controls for arm length and arm width to keep toolbar footprint smaller
• Increased maximum crosshair arm length from 48 to 96 for longer cursor arms
• Switched draw-mode crosshair rendering to a canvas overlay to keep long cursor arms stable at larger sizes
• Lowered minimum crosshair arm width from 1.0 to 0.5 for finer cursor thickness tuning

Fixed

• Prevent drawing from starting outside image bounds
• Constrain in-progress drawing to image boundaries (including auto-pan updates), so boxes cannot be dragged past image edges
• Fixed crosshair shrinking at larger arm lengths due browser cursor image-size limits
• Center images by default in the canvas viewport (including zoom reset)
