ci: Use native platform for win-cross task
What changed, and why it matters
This commit removes a single line from a Bitcoin Core continuous integration (CI) configuration file. The removed line forced the Windows cross-compilation CI task to run on the linux/amd64 platform. After the change, the CI task will use the CI runner's native platform instead. This is a build-infrastructure tweak with no apparent effect on the Bitcoin Core software that end users run.
No security action required. Treat as a normal CI/maintenance change.
Security signals we found
No strong security signals were identified.
Evidence from the diff
In ci/test/00_setup_env_win64.sh, the line export CI_IMAGE_PLATFORM="linux/amd64" is deleted. This environment variable previously pinned the Docker image platform for the Windows cross-compile CI job to amd64. Removing it lets the CI system default to the host’s native platform. The change is purely in CI orchestration and does not modify source code, build scripts, consensus logic, networking, wallet handling, or any shipped binary.
