Added

• RopeEditor widget — monospace editor with optional line gutter, divider, line wrapping, and syntax highlighting via re_highlight
• RopeEditorController — text editing, selection, clipboard, IME support, dirty-state tracking, and async file loading (loadFromFile with optional maxChars for huge single-line files)
• FindController — find/replace bar with case-sensitive, regex, and whole-word matching; live highlight updates as the document changes
• UndoRedoController — undo/redo with compound operation merging for rapid typing bursts
• Rust-backed text buffer — Zed-style zed_rope + zed_sum_tree for O(log n) line and offset queries
• Batch FFI APIs — getLineStartOffsetsBatch, getLinesTextBatch, getMinimapDensityBatch, replaceAndCapture, getCursorContext, and cached getImeProjection for low-latency editing and rendering
• Search APIs — full-document, line-range, whole-word, and include/exclude range search, all executed in Rust
• Indentation analysis — style detection and per-line indent queries
• Word navigation — character classes and VS Code-style word boundaries (Ctrl+Arrow, double-click selection)
• LSP offset helpers — UTF-16 ↔ byte conversion and line/column mapping
• Enhanced Dart highlighting — langDartEnhanced mode
• Platform support — Android, iOS, Linux, macOS, and Windows via Cargokit FFI plugin
• Example app — minimal integration demo under example/
• Documentation — API guides in doc/ and Rust build instructions in README

Changed

• Migrated the text buffer from ropey to Zed's rope implementation, eliminating O(n) metrics rebuilds that caused input lag during undo
