feat: type selector overhaul, fuzzy search, address parser, value tracking

Redesign type selector popup with fuzzy subsequence matching, per-category
icons, field summary tooltips, compact chips, and pointer target primitives.
Add address expression parser with arithmetic and register support.
Enable track value changes by default.

 Reclass helps you inspect raw bytes and interpret them as types (structs, arrays, primitives, pointers, padding) instead of just hex. It is essentially a debugging tool for figuring out unknown data structures — either at runtime from a live process, or from a static source like a binary file or crash dump.

+Built with C++17, Qt 6 (Qt 5 also supported), and QScintilla. The entire editor surface is rendered as formatted plain text with inline editing, fold markers, and hex/ASCII previews.
 
 ## Features
 
 - **Structured binary view** — render raw bytes as typed fields (integers, floats, pointers, vectors, matrices, strings, booleans, padding)
 - **Struct & array nesting** — define nested structs and arrays with collapsible fold regions
+- **Enums & bitfields** — define enums and bitfield types with named members, inline editing, and auto-sort
 - **Inline editing** — click to edit type names, field names, values, and base addresses directly in the editor
 - **Undo/redo** — full undo history for all mutations via command stack
+- **Multi-document tabs** — open multiple projects simultaneously in MDI sub-windows
 - **Split views** — multiple synchronized editor panes over the same document
 - **Type autocomplete** — popup type picker when changing field kinds
 - **Hex + ASCII margins** — raw byte previews alongside the structured view
+- **Value history & heatmap** — track value changes over time with color-coded heat indicators
+- **Disassembly preview** — hover over code pointers to see decoded instructions
+- **C/C++ code generation** — export structs as compilable C/C++ headers
+- **Import / export** — PDB import (Windows), ReClass XML import/export, C/C++ source import
+- **Themes** — built-in theme editor with multiple presets
 - **MCP bridge** — expose all tool functionality to AI clients via Model Context Protocol
-- **Plugin system** — extend with custom data source providers via DLL plugins; following ship by default
+- **Plugin system** — extend with custom data source providers via DLL plugins; the following ship by default:
