refactor: Construct Number::Guard from MantissaRange or relevant fields

- Simplifies the function signatures in Guard, because it doesn't need
  to have those values passed in constantly.
- Also simplifies some of the functions because they don't need to store
  values just to pass them to Guard functions.

+Format embedded shell snippets using the shfmt hook configured in
+.pre-commit-config.yaml.
+
+Two shapes are recognised:
+
+* YAML workflow/action files: literal block-scalar runs (`run: |`) and
+  single-line runs (`run: some command`). A single-line run is upgraded to
+  a `run: |` block scalar if shfmt's output spans multiple lines.
+
+* Markdown files: ``` ```bash ``` fenced code blocks.
+
+Any block that shfmt cannot parse is skipped with a warning on stderr, so
+the file is left untouched and surrounding blocks still get formatted.
+
+For each occurrence the body is dedented, written to a temp .sh file,
+formatted via `pre-commit run shfmt --files <temp>` (falling back to
+`prek`), then re-indented and written back in place.
+
+When invoked without arguments, every .yml/.yaml under .github/ plus every
+.md file in the repo is scanned. When invoked with file arguments (the
+pre-commit case), only those files are processed.

-   Configure sanitizers based on environment variables.
+   Apply sanitizer flags built by the Conan profile.
 
-   This module reads the following environment variables:
-   - SANITIZERS: The sanitizers to enable. Possible values:
-     - "address"
-     - "address,undefinedbehavior"
-     - "thread"
-     - "thread,undefinedbehavior"
-     - "undefinedbehavior"
+   Parsing, validation, and flag construction are performed in conan/profiles/sanitizers.
+   This module reads the following CMake variables injected by the Conan toolchain via extra_variables:
 
-   The compiler type and platform are detected in CompilationEnv.cmake.
-   The sanitizer compile options are applied to the 'common' interface library
-   which is linked to all targets in the project.
+   - SANITIZERS:                The active sanitizers (e.g. "address,undefinedbehavior").
+   - SANITIZERS_COMPILER_FLAGS: Space-separated compiler flags.
+   - SANITIZERS_LINKER_FLAGS:   Space-separated linker flags.
 
-   Internal flag variables set by this module:
-
-   - SANITIZER_TYPES: List of sanitizer types to enable (e.g., "address",
-     "thread", "undefined"). And two more flags for undefined behavior sanitizer (e.g., "float-divide-by-zero", "unsigned-integer-overflow").
-     This list is joined with commas and passed to -fsanitize=<list>.
-
-   - SANITIZERS_COMPILE_FLAGS: Compiler flags for sanitizer instrumentation.
-     Includes:
-     * -fno-omit-frame-pointer: Preserves frame pointers for stack traces
-     * -O1: Minimum optimization for reasonable performance
-     * -fsanitize=<types>: Enables sanitizer instrumentation
-     * -fsanitize-ignorelist=<path>: (Clang only) Compile-time ignorelist
-     * -mcmodel=large/medium: (GCC only) Code model for large binaries
-     * -Wno-stringop-overflow: (GCC only) Suppresses false positive warnings
-     * -Wno-tsan: (For GCC TSAN combination only) Suppresses atomic_thread_fence warnings
-
-   - SANITIZERS_LINK_FLAGS: Linker flags for sanitizer runtime libraries.
-     Includes:
-     * -fsanitize=<types>: Links sanitizer runtime libraries
-     * -mcmodel=large/medium: (GCC only) Matches compile-time code model
-
-   - SANITIZERS_RELOCATION_FLAGS: (GCC only, x86_64 only) Code model flags for linking.
-     Used to handle large instrumented binaries on x86_64:
-     * -mcmodel=large: For AddressSanitizer (prevents relocation errors)
-     * -mcmodel=medium: For ThreadSanitizer (large model is incompatible)
-     On ARM64, these flags are omitted since GCC does not support
-     -mcmodel=large with -fPIC, and -mcmodel=medium does not exist.
+   The flags are applied to the 'common' interface library which is linked to all targets in the project.

 #### Install dependencies
 
-The `SANITIZERS` environment variable is used by both Conan and CMake.
+The `SANITIZERS` environment variable is used during `conan install` command.
 
 ```bash
-export SANITIZERS=address,undefinedbehavior
-# Standard build (without instrumenting dependencies)
-conan install .. --output-folder . --build missing --settings build_type=Debug
-
-# Or with sanitizer-instrumented dependencies (takes longer but fewer false positives)
-conan install .. --output-folder . --profile:all sanitizers --build missing --settings build_type=Debug
+SANITIZERS=address,undefinedbehavior conan install .. --output-folder . --build missing --settings build_type=Debug --profile:all sanitizers
 ```
 
-[!CAUTION]
-Do not mix Address and Thread sanitizers - they are incompatible.
-
-Since you already set the `SANITIZERS` environment variable when running Conan, same values will be read for the next part.
-
-#### Call CMake
-
-```bash
-cmake .. -G Ninja \
-    -DCMAKE_TOOLCHAIN_FILE:FILEPATH=build/generators/conan_toolchain.cmake \
-    -DCMAKE_BUILD_TYPE=Debug \
