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.

This commit lays the foundational groundwork for the artichoke language
parser by introducing the formal language grammar specification.
The tokenizer was updated to include new operators and keywords, also
added the posibility to handle comments.
Key Additions:
- Implemented support for C-style block comments (`/* ... */`),
including error handling for unclosed comments.
- Added all necessary tokens for missing keywords (e.g., `module`,
`export`, `using`, `match`, `loop`) and operators (e.g., `+=`, `:=`,
`.#`, `.*`, `.@`).
- The `Token` enum has been expanded to reflect the full language
feature set.
Documentation:
- Added `docs/grammar.ebnf` which contains the official, well-structured
EBNF grammar for the language.
- Added `docs/readme.md` providing a detailed technical overview of the
language's features, syntax, and semantics.
BREAKING CHANGE: The `kwVariant` and `kwMut` tokens have been removed to
align with the updated language design defined in the new grammar.
Fixed some minor mistakes (wrong messages/errors) due to copy/pasting
code.
Fixed that digits weren't allowed in identifiers before.
Also minor improvements in some functions/code parts.
Initial version of Tokenizer and Token
Generator template for coroutines (used in tokenizer)
Utilities like string related functions, TrieMap, and error handling
