Use the x64 Windows espflash asset on Windows ARM64.

x86_64_arch maps Windows ARM64 to aarch64, so this pattern requests espflash-aarch64*pc*. espflash v4.7.0 publishes only espflash-x86_64-pc-windows-msvc.zip for Windows. Because espflash is in the base tool set, a full mise install can fail before any firmware task runs.

The current Windows ARM CI lane avoids this path by using MISE_ENV=rust and installing only selected tools.

Suggested fix

Review comment at @.mise/config.toml at line 534:
Update the espflash_glob asset pattern so Windows uses the x86_64 asset
architecture even on ARM64, while Linux and macOS continue using x86_64_arch.
Preserve the existing OS-specific suffix matching.
