MinML tree-sitter parser

[phamelink]

This PR introduces a Tree-sitter grammar for MinML, enabling high-performance incremental parsing and laying the foundation for advanced editor support such as syntax highlighting, code folding, and symbol
navigation.

Key Changes

• Grammar Implementation: Added dev/tree-sitter/grammar.js which defines the MinML syntax, including support for elements, attributes, character references, quoted strings, raw blocks, and matcher escapes.
• Comprehensive Test Suite: Created a test corpus in dev/tree-sitter/test/corpus/minml.txt with 30 test cases:
  • 12 success cases covering all standard MinML features and complex nesting.
  • 18 error cases demonstrating robust error recovery and AST generation for invalid inputs.
• Developer Documentation: Added dev/tree-sitter/README.md with detailed instructions on the project structure, how to regenerate the parser, and how to run tests.
• Build System Integration: Updated the root Makefile to include tree-sitter-gen and tree-sitter-test targets for a streamlined developer workflow.
• Project Documentation: Updated the root README.md and dev/README.md to include the Tree-sitter tool in the project overview.
• Reference Examples: Added dev/tree-sitter/examples/13-error-cases.m as a reference for known invalid input patterns.

Verification

The implementation has been verified by running the Tree-sitter test suite make tree-sitter-test and also manually checking the outputs of parsing example files with tree-sitter parse examples/XX-XX.m

As this is the most important file of the PR, comments explaining how you structured the grammar is important.

Is this just the setup or is it implemented in the extension ?

Also, it might be better to remove the generated files and have the consumer download tree sitter locally to regenerate the files.
