248b9cf3d0 perf: implement canvas pooling to reduce memory allocations 
Replace per-iteration canvas creation with a reusable canvas pool:

- Pre-allocate 6 canvas objects (max needed for split=5 strategy)
- Reuse canvases across all split strategies by resizing
- Set unused canvases to 0×0 to free bitmap memory
- Reduces allocations from ~36 to 6 objects (83% reduction)

Benefits:
- Lower memory footprint
- Reduced GC pressure
- Better performance (resize vs allocate)
- More deterministic memory usage

09c4cca67b feat: implement horizontal slicing strategy for improved PDF417 detection 
Improve barcode detection in documents with graphics and text by implementing
a multi-strategy horizontal slicing approach:

- Split documents into overlapping horizontal sections (5,4,3,2,1, or full)
- Decode each section separately to isolate individual barcodes
- Use 2% overlap between sections to avoid missing boundary codes
- Return the strategy that detects the most barcodes
- Early exit optimization when fewer codes are found

Also fix error handling to use Error objects instead of string literals.

fcc1ede4d0 refactor: simplify barcode detection by removing canvas splitting 
Remove canvas splitting logic since zxing-wasm natively supports multiple barcode detection with maxNumberOfSymbols parameter. Reduces code by 69 lines and improves performance by requiring only a single decode call per canvas. Set maxNumberOfSymbols to 10 for realistic utility bill use case.

5b0497891a feat: migrate PDF417 barcode decoder from @zxing/browser to zxing-wasm 
Replace @zxing/browser with zxing-wasm for better performance and smaller WebAssembly bundle size (919KB). Added middleware exclusion for .wasm files to prevent i18n routing interference.
