Implement TypeExpression AST node to allow types to be used within
expressions, enabling the parsing of anonymous slice and array
initializers like `[]Type { ... }`.
- Register `[` as a prefix-style token (NUD) in the Pratt parser.
- Add `TypeExpression` node to AST and expression variants.
- Update `toDot` and `toString` visitors for AST visualization.
- Update frontend to open source files directly to fix issues at opening
paths.

Major refactoring of the Parser and Tokenizer components to improve code
maintainability, strengthen error messaging, and streamline AST
generation.
This version intentionally focuses on top-level declarations, with
statement parsing stubbed for the next development phase.
- **Path Sanitization**: Added `sanitizePath` to extract filenames from
input paths, ensuring consistent `unitName` identification regardless
of directory depth.
- **Improved Output**: Wrapped AST string output in Markdown code blocks
and added a commented-out entry for the new DOT graph visualization.
- **Unified Consumption**: Replaced manual token checks with a more
robust `consume()` method that leverages `peekExpect()` for
centralized error handling.
- **New Predicates**: Introduced `match()` and `matchAndConsume()`
helpers to handle optional tokens and branching logic without
redundant peek/consume calls.
- **Exception Handling**: Standardized the use of `langException` across
all parsing functions, providing more descriptive "Expected X, found
Y" messages.
- **Declarations**: Refactored `parseTopLevelDeclaration` and
sub-parsers (Module, Struct, Enum, Fn) to use the new matching
patterns.
- **Looping Logic**: Replaced recursive-style parsing loops with
`while(keepParsing)` iterative blocks to prevent stack depth issues
and clarify termination conditions (e.g., finding a closing brace or
failing to find a comma).
- **Namespaced Identifiers**: Rewrote `parseNamespacedIdentifier` to
correctly handle multi-part paths (`A::B::C`) and edge cases.
- **Generic Support**: Improved handling of generic parameter and
argument lists, ensuring strict enforcement of delimiters like `<` and
`>`.
- **Contextual Errors**: Updated `peekExpect` to accept a custom
`message` string, allowing the parser to describe *what* it was
looking for (e.g., "Expected ';'").
- **Token Lookahead**: Enhanced `peek` and `peekExpect` reliability with
better bounds checking and buffer management.
- **Removed `lib/src/Parser/AST/AST.cpp`**: Deleted the monolithic AST
stringification file in favor of the previously introduced modular
implementations.
- **Build System**: Updated `.gitignore` to ignore
`cpm-package-lock.cmake`.

This commit introduces a comprehensive test suite for the tokenizer
using the Catch2 framework. To support this and improve the project
structure, the build system and the tokenizer's API have been
significantly updated.
- Removed `cmake/testing.cmake` as it's no longer needed.
- A new `TokenizerRange` class provides a C++20-style range interface,
allowing for simple `for-each` loop iteration over tokens. This is
used extensively in the new tests.
- The CMake build system has been refactored:
- An `ENABLE_TESTING` option (OFF by default) now controls whether
the test suite is built.
- The core library is now compiled into an object library, which is
then used to produce both a shared (`.so`/`.dll`) and a static
(`.a`/`.lib`) library. This improves build efficiency and provides
more flexible linkage options.
- The frontend executable now links against the static version of
the library.
- Implemented tests for tokenizer using Catch2 framework, covering
various cases like identifiers, keywords, numbers, etc. that already
catched some issues in current implementation.
- Several parsing bugs and edge cases in the tokenizer were fixed,
including the handling of unterminated strings and invalid numeric
literals. The README has been updated with instructions for building
and running tests.
