Add 4 watermark/overlay tools with API routes and frontend settings:
- watermark-text: SVG text overlay with tiling, position, opacity, rotation
- watermark-image: logo/image watermark with position, opacity, scale
- text-overlay: styled text on images with shadow and background box
- compose: layer images with position, opacity, and blend modes
Draggable split-view slider with clip-path reveals original vs processed
image. Shows file size badges with savings percentage. Supports pointer
events for both mouse and touch. Integrated into tool-page to replace
dropzone after processing completes. Updated file-store with
originalBlobUrl for comparison. Enhanced dropzone with multi-file count
badge and file list display.
Adds Zustand file store, useToolProcessor hook for upload/process/download
flow, and 7 settings components: resize (with social media presets), crop
(with aspect ratio presets), rotate/flip, convert, compress (quality +
target size modes), strip-metadata, and color adjustments (brightness,
contrast, saturation, channels, effects). Updates tool-page to render the
appropriate settings panel based on toolId.
