跟踪 drop environment-dev-win-arm64.yml 所需的 conda-forge win-arm64 包

These are listed in environment-dev.yml (or required by tests / static CI) and cannot currently be installed from conda-forge for win-arm64:

Package	Why we need it	Notes
cxx-compiler	libmamba / micromamba build	Replaced by vs2022_win-arm64 plus ilammy/msvc-dev-cmd in CI
pkg-config	CMake dependency discovery	Migration PR: conda-forge/pkg-config-feedstock#49
make	Unix build helper in environment-dev.yml	Optional on Windows (Ninja is used)
cryptography	dependency of conda-content-trust and mitmproxy	No win-arm64 build; also blocked upstream: pyca/cryptography#14293
bcrypt	pinned extra for mitmproxy	No win-arm64 build
mitmproxy	micromamba/tests/test_proxy.py (mitmdump)	noarch, but unsolvable without cryptography / bcrypt
conda-content-trust	signed-repo tests (micromamba/test-server/reposerver.py)	noarch, but unsolvable without cryptography
mypy	libmambapy stub generation	Current builds do not solve with Python 3.14 on win-arm64
doxygen	documentation	No win-arm64 build
binutils	PE/DLL check in the Windows static build	No win-arm64 build; previous attempt: conda-forge/binutils-feedstock#89

Python on this platform is currently 3.14 (and experimental 3.15). environment-dev-win-arm64.yml pins Python=3.14 for that reason.
