Move the over-long path mapping into a process-wide DirectoryMapper
in Path, exposed as aTryGetShortPath(). SpiceAPI keeps using it for
kernels; IGRF now maps its data directory too, since
SetCurrentDirectoryW rejects paths beyond MAX_PATH - 2. Drop the
CI-only skips from the magnetosphere tests and cap the dependency
install step at 60 minutes.

The change adds shared temporary directory aliases for short-path handling. SpiceAPI and Windows IGRF use the helper for long paths. Magnetosphere tests no longer skip outside GitHub CI, and a workflow step has a 60-minute timeout.
Changes: Short-path handling
Layer / File(s)
Summary
Directory alias mapping src/AstUtil/Platform/Path.hpp, src/AstUtil/Platform/Path.cpp
Adds cached directory aliases using junctions on Windows or symbolic links on POSIX. Adds short-path functions and cleanup for the alias root.
SpiceAPI converts paths to CRT encoding and tries short paths for paths over 255 characters. Windows IGRF tries a short path when its absolute data-directory path exceeds MAX_PATH - 2.
Magnetosphere test coverage test/weather/testMagnetosphere.cpp
The igrf13, aep8, igrf, and get_flux tests no longer skip outside GitHub CI.

Merge Risk: High · up to 7e7ee
The short-path helper likely does not compile on Windows, which is the platform it targets. It can also return an alias to the wrong directory after the working directory changes. Filesystem errors can crash the process instead of falling back to the original path. The CI workflow also lacks explicit token permissions. Fix these before merging.

igrf_field builds the same datadir and changes the working directory into it. It does not use the MAX_PATH - 2 check that this PR adds to igrf. On Windows with a long data-directory path, igrf_field still fails in SetCurrentDirectoryW. This is the failure the PR fixes for igrf.
Extract the Windows block into a shared helper and call it from both functions.
Then use fs::path datadir = igrfDataDir(); in both igrf and igrf_field.

Fix the -Werror=effc++ build failure: initialize mutex_ with a default member initializer.
The xmake -ay Linux arm64 job fails at Line 347. DirectoryMapper() = default; leaves mutex_ without an initializer, and -Werror=effc++ turns that warning into an error. SpiceAPI already uses std::mutex mutex_{}; for the same reason.

shortPathAliases_ stores std::string keys and values, but this call passes two fs::path objects. On Windows, fs::path uses std::wstring as its native string type, so this cannot construct the map entry and the Windows build fails. (en.cppreference.com)
Use path.string() and aliasDir.string(), or store fs::path objects in the map.

Update the shortPathAliases_ insertion to pass string keys and values by

Major · Key aliases by resolved absolute paths. · Path.cpp:371-375
The cache uses the original path spelling before fs::absolute() runs at Line 405. If a relative path is mapped under one current directory and the process changes its current directory, the same relative path returns the old directory's alias. SpiceAPI::makeSpicePath() passes its input directly to this helper, so relative inputs are not excluded.
Resolve and normalize the path before the cache lookup. Use that resolved path for both the cache key and alias target.

Update the cache lookup in the visible `Path` helper to resolve and normalize
`dirpath` before using it; use that resolved path as both the
`shortPathAliases_` key and the alias target so relative paths are tied to their
absolute location.
Minor · Handle cleanup errors without throwing. · Path.cpp:391-392
Both fs::remove_all() calls use the throwing overload. A stale alias root that cannot be removed causes getShortPath() to throw instead of using the documented fallback. The same exception from releaseShortPathAliases() can escape the noexcept destructor and terminate the process.
Use the std::error_code overload and preserve the fallback behavior when cleanup fails.

Path.cpp uses fs:: and aWarning without including the headers that
declare them; include them directly.
Default-initialize mutex_ in its declaration, which is what
-Werror=effc++ on the GCC/MinGW builds wants.
The cache uses path.string() as its key, but the alias targets fs::absolute(path). If a relative path is mapped from one working directory, then reused after the working directory changes, the cache returns the alias for the old directory. Normalize the path before lookup and insertion. (raw.githubusercontent.com)

Major · Keep filesystem failures on the fallback path. · Path.cpp:395
fs::remove_all(shortPathRoot_) uses throwing overloads during setup and teardown. A cleanup failure can escape getShortPath(), and the destructor can terminate the process. fs::is_directory(p) can also throw for an inaccessible path instead of returning the original path. Use std::error_code overloads and make cleanup best effort. (raw.githubusercontent.com)
