The __pycache__ directory was being tracked by git, causing compiled Python bytecode files like env.cpython-312.pyc to appear in the repository. This change adds __pycache__ to .gitignore and removes the existing pyc file from version control.
Add 'books' to .gitignore to exclude it from version control, and include generated Rust build fingerprint files for crossbeam-deque, crossbeam-epoch, crossbeam-utils, either, and rayon dependencies under 12bitfloat_rust/risspam/target/release/.fingerprint/
Introduce four boolean flags (show_capitalized, show_sentences, show_words, show_numbers) that control whether their respective analysis results are printed via sld(), replacing the previously commented-out calls. Add a file_exists() utility function that checks if a given path points to an existing readable file. Also append "publish" to .gitignore.
Add the complete source tree for the isspam spam detection utility, including the main C implementation (isspam.c), custom memory allocator (rmalloc.h), string builder (rstr.h), dynamic string list (rstring_list.h), build configuration (Makefile, .clang-format), CI workflow (.gitea/workflows/build.yaml), and sample test data (spam/examole_spam3.txt, not_spam/correct1.txt). The core logic defines a list of forbidden words and provides functions for tokenizing input, removing preserved characters, and checking content against the spam keyword set.
