Finch 1.0.0

A small, fast programming language on LLVM with C-like syntax.

- Lexer, recursive-descent parser, single-pass type checker + LLVM IR codegen, O2 pipeline
- Types: int/float/bool/char/str, sized i8..u64/f32/f64, pointers ptr[T] with addr()/.value/null
- Functions (fn ... -> T), if/else, while, for..in, break/continue, Go-style operator precedence
- Implicit conversions only when lossless; literals adapt to their target type
- Runtime checks for division by zero, MIN/-1 and null .value
- C interop: import "header.h" via libclang, link "lib" with pkg-config, link-error advice
- Human-readable errors with source excerpts
- Test suite (34 tests), examples, docs for beginners/technicians/engineers in English and Polish
