Fixes#18556 by using RUSTC_WRAPPER instead of setting RUSTFLAGS directly.
This allows Homebrew's optimization flags to coexist with .cargo/config.toml
settings, preventing build failures when projects have their own Rust
configuration.
- Add rustc_wrapper shim that clears RUSTFLAGS and prepends HOMEBREW_RUSTFLAGS
- Update both std and super environments to use RUSTC_WRAPPER
- Store Homebrew's rustflags in HOMEBREW_RUSTFLAGS instead of RUSTFLAGS

While filing https://github.com/Homebrew/brew/issues/20379, I lost where I was because I followed the given instruction. Instead, let's use pushd/popd so the user is returned to their pwd if the git operations succeed.
The library_paths method was using readlines which could leave file
descriptors open due to Ruby's garbage collection behavior. When
processing many packages during 'brew upgrade' or 'brew linkage',
this caused "Too many open files" errors on Linux systems.
Changes:
- Replace readlines with explicit file.open block to ensure proper closure
- Add caching to avoid repeatedly reading /etc/ld.so.conf during a session
- Cache included files as well to optimize recursive include processing

Fixes#20374
When using HOMEBREW_DOWNLOAD_CONCURRENCY, cask binaries were being
downloaded before checking if the cask could actually be installed
(e.g., disabled casks or conflict checks). This resulted in unnecessary
downloads for casks that would ultimately fail to install.
This change adds a `prelude` method to Cask::Installer that performs
early validation checks (deprecation/disable status and conflicts)
similar to Formula#prelude_fetch. The prelude method is called before
enqueueing downloads in all download queue scenarios (install, reinstall,
and upgrade commands), ensuring that validation failures occur before
the "Fetching downloads for:" message is displayed.
Key changes:
- Add Cask::Installer#prelude method with @ran_prelude tracking
- Call prelude before enqueueing downloads in install/reinstall/upgrade
- Refactor to avoid creating installer objects multiple times
- Maintain backward compatibility for non-download-queue scenarios
