v0.2.0 — Tree-sitter parsers, 11 languages

What's new

Tree-sitter AST parsing replaces all regex parsers. Stacklit now uses a pure Go tree-sitter runtime for accurate extraction across 11 languages.

Language support

Language	Parser	Extracts
Go	stdlib AST	imports, exports, types, struct fields
TypeScript/JS	tree-sitter	imports, exports, classes, interfaces, types
Python	tree-sitter	imports, classes, methods, type hints, entrypoints
Rust	tree-sitter	use/mod/crate, pub items, traits, generics
Java	tree-sitter	imports, public classes, method signatures
C#	tree-sitter	using directives, public types, methods
Ruby	tree-sitter	require, classes, modules, methods
PHP	tree-sitter	namespace use, classes, traits, methods
Kotlin	tree-sitter	imports, classes, objects, functions
Swift	tree-sitter	imports, structs, classes, protocols
C/C++	tree-sitter	includes, functions, structs, typedefs

Other improvements

• list_modules MCP tool -- agents can now discover all modules
• MCP cache invalidation -- index reloads when stacklit.json changes on disk
• Table view search/filter input
• DEPENDENCIES.md replaces stacklit.mmd -- renders on GitHub
• Real-world examples: Express.js, FastAPI, Gin, Axum (see examples/)
• Demo GIF in README
• Node richness tiers in graph visualization
• HiDPI canvas rendering

Token efficiency (measured)

Project	Lines of code	Index tokens
Express.js	21,346	3,765
FastAPI	108,075	4,142
Gin	23,829	3,361
Axum	43,997	14,371
