1.0.0 - 2026-04-11 #

Core TOON Engine: Full implementation of the Token-Oriented Object Notation encoder and decoder for Dart.
Deep Tabularization: Automatic flattening of nested uniform objects into single-line tabular headers (e.g., user.address.street). Achieves ~40% token savings on complex datasets.
Smart Sequences: Support for non-tabular lists of objects without markers, using "Duplicate Key" detection to identify item boundaries.
Validation & Linting API: Added validateToon and ToonLintError to catch structural issues like inconsistent indentation or truncated arrays.
CLI Tool: A command-line utility for developers (bin/toon.dart):
- validate: Quick structural check.
- lint: Inline error reporting with comments on problematic lines.
- decode: Parse and view resulting JSON structure.
Improved Examples: Added example.dart (simple hikes) and users_example.dart (complex nested users) to demonstrate different output modes.
Documentation: Detailed README.md and a comprehensive usage.md guide.

Type Fidelity: Fixed an issue where strings starting with numbers were misinterpreted as numeric types; these are now correctly quoted.
Key Stability: Removed automatic alphabetical sorting of keys to preserve the original insertion order of the data.
Indentation Strictness: Improved the decoder to be more graceful with root-level indentation in certain CLI edge cases.
