* feat: add MCP Apps receipt matcher widget for inline receipt-to-transaction matching
Adds an interactive HTML widget that renders inline in Claude Desktop via MCP Apps
(SEP-1865), letting users drag receipts onto uncategorized transactions to categorize,
book, and attach documents in one flow without leaving the conversation.
- Extract categorizeTransactionCore() shared by both categorization tools
- Add gnubok_receipt_matcher tool with _meta.ui for MCP Apps widget rendering
- Add gnubok_categorize_with_receipt tool (categorize + upload document)
- Add resources/list and resources/read protocol handlers
- Self-contained widget HTML with MCP Apps bridge, drag-and-drop, client-side resize

* fix: address review feedback — buffer slice, MIME type, HTML escaping
- Fix Buffer.buffer slab pool issue: slice to exact byte range to avoid
corrupted uploads for small files (≤4096 bytes)
- Update MIME type to image/jpeg after canvas re-encode (was keeping
original file.type, causing content-type mismatch in DB)
- Escape tx.date through esc() for consistent innerHTML sanitization
- Remove unused `reset` variable in tests
