The CI workflow was sourcing the cargo binary directory ($HOME/.cargo/bin) instead of the environment setup script ($HOME/.cargo/env), which prevented proper initialization of Rust toolchain paths during build steps.
Add curl to apt install list and install Rust nightly via rustup in the CI workflow. Update Makefile all target to include build_risspam before run_risspam, ensuring the Rust-based risspam binary is compiled before execution.
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.
