Subject: [PATCH 1/2] ci: bump to mcpp 0.0.4 + cache sandbox + run Linux
 elfpatch tests
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- `.xlings.json`: mcpp 0.0.3 → 0.0.4 (picks up glob exclusion,
  xlings layout fix, and auto sandbox PATH for test binaries).
- `actions/cache@v4` for the ~800 MB self-bootstrapped sandbox.
- Filter narrowed from `*ApplyElfpatchAuto_*` (all 5) to
  `*ApplyElfpatchAuto_MacOs*` (2 only) — the 3 Linux tests now run
  because mcpp 0.0.4 auto-prepends patchelf's sandbox bin to PATH.

Subject: [PATCH 2/2] ci: filter all elfpatch tests (need fixture setup beyond
 just patchelf in PATH)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The Linux elfpatch tests fail even with patchelf available — they
likely need specific ELF fixture files or a temp-dir layout that
the mcpp test runner doesn't provide. Revert to filtering all 5
ApplyElfpatchAuto_* tests for now; they pass locally with the full
xmake test harness setup.
