fix: cross typos detail below:

What I did
Repository rules / exclusions
I didn’t find repo-specific spelling tooling already in place (no existing codespell config).
Given this is a C/C++ repo with vendored sources, I treated src/3rdparty/** as third-party and excluded it from typo fixing (and encoded that in the new .codespellrc).
Typos fixed (first-party only)
Docs
CHANGELOG.md: perfomance -> performance
doc/API.md: optionaly -> optionally, Offical -> Official
doc/BENCHMARK.md: parameteres -> parameters
doc/CPU.md: loosing -> losing, instuctions -> instructions
doc/CHANGELOG_OLD.md: multiple obvious text typos like Breaked -> Broken, singal -> signal, previos -> previous, secons -> seconds, automaticaly -> automatically, perfomance -> performance
Code comments / doc comments (safe text-only changes)
src/base/crypto/sha3.cpp: Inteface -> Interface (comment banner)
src/backend/opencl/cl/cn/cryptonight.cl: performe -> perform, crashs -> crashes (comments)
src/backend/opencl/cl/kawpow/kawpow.cl: regsters -> registers, intial -> initial (comments)
src/crypto/randomx/aes_hash.cpp: intial -> initial (comment)
src/crypto/randomx/intrin_portable.h: cant -> can't (comment)
src/crypto/randomx/randomx.h: intialization -> initialization (doc comment)
src/crypto/cn/c_jh.c: intital -> initial (comment)
src/crypto/cn/skein_port.h: varaiable -> variable (comment)
src/backend/opencl/cl/cn/wolf-skein.cl: Build-in -> Built-in (comment)
What I intentionally did NOT change
Anything under src/3rdparty/** (vendored).
A few remaining codespell hits are either:
Upstream/embedded sources we excluded (groestl256.cl, jh.cl contain Projet)
Potentially valid identifier/name (Carmel CPU codename)
Low-risk token in codegen comments (vor inside an instruction comment)
These are handled via ignore rules in .codespellrc instead of modifying code.

Added: .codespellrc
Created /.codespellrc with:

skip entries for vendored / embedded upstream areas:
./src/3rdparty
./src/crypto/ghostrider
./src/crypto/randomx/blake2
./src/crypto/cn/sse2neon.h
./src/backend/opencl/cl/cn/groestl256.cl
./src/backend/opencl/cl/cn/jh.cl
ignore-words-list for:
Carmel
vor
Verification
codespell . --config ./.codespellrc now exits clean (exit code 0).
