fix: 更新 Galay 至 5.0.1

[gzj-creator]

Summary

• Update the gzj-creator.galay Form-A descriptor from 5.0.0 to 5.0.1.
• Pin the v5.0.1 GitHub GLOBAL archive (be864cf9467188c231cd69baed496c73d7e4bd29234b9349b284238576f14b77). GitCode CN mirror setup remains deferred as requested; the descriptor keeps the documented GLOBAL fallback.
• Keep the Unix workspace example focused on the default galay.utils and galay.kernel module surface.
• Refresh the English/Chinese descriptor catalogs, changelog, and design record.

Why this reruns CI

The previous 5.0.0 run failed in the Linux LLVM and macOS jobs because the generated module prelude unconditionally reached intrin.h/emmintrin.h. Galay 5.0.1 adds the upstream compiler/architecture guards for those headers.

Local validation

• mcpp test -p galay (default GCC): test result ok. 1 passed; 0 failed
• CI-pinned mcpp 2026.8.27.2 test -p galay (GCC 16.1.0): test result ok. 1 passed; 0 failed
• Descriptor lint checks and full pinned mcpp xpkg parse pass.

The example intentionally does not claim coverage for optional SSL, HTTP, database, RPC, MCP, tracing, or other feature-gated modules. Windows remains absent from the package descriptor because upstream v5.0.1 declares Linux/macOS only; the no-op example path is retained there.

CI rerun result for commit 4acf1b2 (run 33269750913):

• Passed: Linux default, macOS default, Windows default, lint, select, mirror-cn-reachable, graphics side-effect, build, timings.
• Failed: Linux LLVM (workspace (linux llvm 0/1)).

The v5.0.0 intrinsic-header failure is fixed in v5.0.1. The remaining LLVM failure is in the upstream galay-kernel source: Clang 22 rejects async_aio.h:288 (cannot export 'await_suspend' as it is not at namespace scope) and then reports invalid member accesses. This happens while compiling galay.kernel before the consumer test runs; GCC and macOS pass.
