Add workflow-level concurrency to the direct GitHub Actions entrypoints so a
newer run for the same pull request or repository ref cancels the older
in-progress run.
Keep the reusable workflow graph, release guards, triggers, and permissions
unchanged while documenting the concurrency policy and the official GitHub
references used for the change.

Pin every external action used by the root GitHub workflow set to a full-length
commit SHA and keep the selected release tag as a same-line comment.
Update the root workflows to the latest stable tagged action versions found
during the audit while preserving existing release guards, permissions, and
reusable workflow wiring.

Improve `get_native_properties.sh` with a refreshed implementation.
The new version covers all Makefile ARCH variants and keeps the
script interface stable while improving portability and CPU feature
detection across supported platforms. Drop the asset file name to
avoid coupling outputs to a specific artifact naming scheme.

WINE_PATH started as a Wine-specific knob, but it’s now used more generally
as a command prefix to run the built engine under wrappers
like Intel SDE, qemu-user, etc.
- Add RUN_PREFIX as the supported “run wrapper/prefix” variable in Makefile
- Set WINE_PATH as a deprecated alias
- Update CI and scripts to use RUN_PREFIX

- loop through the commits starting from the latest one
- read the bench value from the last match, if any, of the template
in the commit body text

- set the variable only for the required tests to keep simple the yml file
- use NDK 21.x until will be fixed the Stockfish static build problem
with NDK 23.x
- set the test for armv7, armv7-neon, armv8 builds:
- use armv7a-linux-androideabi21-clang++ compiler for armv7 armv7-neon
- enforce a static build
- silence the Warning for the unused compilation flag "-pie" with
the static build, otherwise the Github workflow stops
- use qemu to bench the build and get the signature
Many thanks to @pschneider1968 that made all the hard work with NDK :)

have maximal compatibility on legacy target arch, now supporting AMD Athlon
The old behavior can anyway be selected by the user if needed, for example
make -j profile-build ARCH=x86-32 sse=yes

A Windows Native Build (WNB) can be done:
- on Windows, using a recent mingw-w64 g++/clang compiler
distributed by msys2, cygwin and others
- on Linux, using mingw-w64 g++ to cross compile
Improvements:
- check for a WNB in a proper way and set a variable to simplify the code
- set the proper EXE for a WNB
- use the proper name for the mingw-w64 clang compiler
- use the static linking for a WNB
- use wine to make a PGO cross compile on Linux (also with Intel SDE)
- enable the LTO build for mingw-w64 g++ compiler
- set `lto=auto` to use the make's job server, if available, or otherwise
to fall back to autodetection of the number of CPU threads
- clean up all the temporary LTO files saved in the local directory
Tested on:
- msys2 MINGW64 (g++), UCRT64 (g++), MINGW32 (g++), CLANG64 (clang)
environments
- cygwin mingw-w64 g++
- Ubuntu 18.04 & 21.10 mingw-w64 PGO cross compile (also with Intel SDE)
