Fix review observations from GPT 5.6-Sol by propagating setup and registration failures, making downloads fail reliably, using portable sed syntax, and preserving diagnostic state. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
Note that isal and mpir still want host yasm but they are excluded on arm64-osx, and should they ever be touched again they should be switched to the `yasm` port rather than host bits given that official yasm releases have memory corruption bugs.
Update pinned versions: - macosvm 0.2-2 -> 0.2-3 - macOS 26.4.1 (25E253) -> 26.6 (25G72) - Xcode and Command Line Tools -> 26.6 - PowerShell 7.x -> 7.6.4 - Azure Pipelines agent 4.266.2 -> 5.276.0 - Node.js 22.x -> 24.x Also remove the obsolete Parallels directory layer while preserving vcpkg-osx filesystem names and PrOsx Azure DevOps pool names.

Well, pkgconf is reasonable C code ;-) Waiting for llvm. |

The macOS 26.6 / Xcode 26.6 image enables newer C and C++ diagnostics and exposes several assumptions in older upstream sources. - bde: exempt Apple Clang from the sized-deallocation feature-macro assertion because Apple Clang implements the feature without defining the macro. - glpk: keep the legacy bool definitions before C23, but avoid redeclaring the C23 bool keyword when compiling in C23 mode. - highs: remove upstream compiler-name preferences so CMake honors the compiler selected by the user or vcpkg toolchain instead of finding an installed LLVM compiler. - krb5: expand the K5_AC_INIT wrapper in configure.ac so Autoconf 2.72 sees AC_INIT directly. - libtar: convert the basename and dirname compatibility functions from K&R definitions to modern prototypes accepted by C23 compilers. - nettle: give the bundled getopt and getenv declarations complete prototypes compatible with the macOS 26.6 SDK. - qt5-location: backport the newer Boost.MPL constant-expression path for its vendored Boost 1.65.1 headers. - rubberband: include stddef.h explicitly so size_t no longer depends on a transitive include.

The M1 mac minis used for the vcpkg build lab are approaching 5 years old which is when the lab folks want to replace them. They've set up M4 mac minis for us to use. The new machines are in a more restricted network configuration which prevents us from SSHing to them -- KVM software only.
