Description
After install vcpkg, is it OK to run vcpkg with specifying path（like $VCPKG_ROOT/vcpkg）. However, add $VCPKG_ROOT into PATH environment variable and run vcpkg, I got an error message.
➜ testproj $VCPKG_ROOT/vcpkg --version
vcpkg package management program version 2999-12-31-unknownhash
See LICENSE.txt for license information.
➜ testproj vcpkg
internal error: /home/niko/vcpkg/buildtrees/_vcpkg/src/vcpkg-tool-2026-05-27/src/vcpkg/base/system.process.cpp(261): Could not determine current executable path.

Research direction
Start at src/vcpkg/base/system.process.cpp:261 and reproduce the difference between invoking vcpkg through $VCPKG_ROOT/vcpkg and through PATH on OpenBSD. Confirm the fix by running both invocation forms and checking that each reports the version or otherwise starts without the current-executable-path error.
