📝 Walkthrough

Walkthrough

Platform gating and static binary checksum handling are updated for additional architectures and shared SHA512SUMS manifests. Clang-tidy formatting and CLI documentation help lookup also receive small ownership-related cleanup changes.

Changes

Downloader platform and checksum handling

Layer / File(s)	Summary
Unified platform gating clang-tools-manager/src/downloader/hashing.rs, clang-tools-manager/src/downloader/static_dist.rs	SHA-512 support and static distribution modules use unified Windows/Linux/macOS and x86_64/aarch64 target conditions.
SHA512SUMS download and verification clang-tools-manager/src/downloader/static_dist.rs	Binary URLs and checksum caching now use a shared SHA512SUMS manifest and match entries by tool path.

Clang-tidy formatting cleanup

Layer / File(s)	Summary
Direct formatting arguments cpp-linter/src/clang_tools/clang_tidy.rs, cpp-linter/src/common_fs.rs	Clang-tidy output formatting removes unnecessary borrowed arguments while preserving generated content.

CLI documentation help lookup

Layer / File(s)	Summary
Subcommand help retrieval docs/src/lib.rs	Subcommand help generation retrieves get_about() directly before missing-value error handling.
