mean, and variance calculations.
The following distributions are implemented:
* Normal
* Uniform
* Exponential

* Optimized adler32 implementations.
- Adapted adler32 implementation from Crypto++ public domain library.
- Added unit tests for adler32 hashing algorithm.
* tabified adler32 implementation to match stdlib.
* Formatting to be consistent. Make unrolling use macro.

* split `test_hash_vector_macro` into per-type functions
it went from a single 18367 instructions function, to eleven separate
functions with (1000 to 1600) instructions each
thats 15649 instructions total, 2718 less instructions overall.

```
* made the `test_hash_vector_internal` generic
* optimize `test_ct_intlog2` while still covering all 128 bit positions
* refactor whirlpool to reduce code bloat
replaced the fully unrolled round loop with a runtime loop, reducing
instruction count by 80k in `process_block` and yielding aprox 30%
performance boost due to improved cache locality.
* use compile-time arrays for `test_ct_intlog2`
* codepage: add single-byte code page support
Add std::encoding::codepage with a shared engine for converting between
single-byte code pages and UTF-8 using table-driven mappings.
Introduce generated tables and wrappers for several code pages[1] each
exposing encode/decode helpers built on a common CodePageTable
structure.
The mapping data is generated by cpgen[2] from the Unicode Consortium’s
published code page mapping files and follows the Unicode standard’s
interpretation of control characters (abstract characters) rather than
historical VGA glyph shapes.

- Group each BSD test in its own subshell. Without this, if an error
occurs, it exits, but we don't know "where" it failed

* refactor(CI): Centralize test logic and fix Docker execution
This commit refactors the GitHub Actions workflow to improve
maintainability and correct a flaw in the Docker build.
- Ensures Docker based tests run *inside* the generated container, not
on the host. This also fixes environment isolation and user permission
errors.
- Centralizes all common test steps (examples, libs, unit tests, etc)
into a single, auto-detecting Bash script: `scripts/tools/ci_tests.sh`.
- Centralize all release artifact packaging into a single
`scripts/tools/package_build.sh`
- fixes using correct paths for test_suite_runner when running on
windows under bash.
- This significantly reduces YAML duplication, making `main.yml` more
readable and easier to maintain.
This one supersedes pull/2677, and includes the fixes for:
- fix openbsd and netbsd
- added win-llvm 21.1.8 and fixed CMakeLists.txt
- added full unit-tests and suite for build-msys2-mingw and
build-msys2-clang

* ci: run tests in temp dir to avoid workspace pollution
Executes ci_tests.sh in a disposable temporary directory by copying
resources/ and test/ folders, preventing build artifacts from cluttering
the source tree.
This makes it easy to run `scripts/tools/ci_tests.sh` locally on any
platform.

This now checks if package already installed trying to prevent
annoying warnings in the github ci:
Fixes:
```
build-mac (Release, 19)curl 8.17.0 is already installed and up-to-date.
To reinstall 8.17.0, run: brew reinstall curl
```
* refactor test_suite_runner
- less allocations, cleaner code, more maintainable.
- now can be killed and the temp dirs are correctly cleaned up, and the
output is correct.
* main.yml: bsd: change to using rsync, is twice as fast.
* default to `--wincrt=dynamic` when `--sanitize=address` on windows
Default to dynamic, as static ASan is removed in LLVM 21+ for Windows
