[zebreus]

Pull request overview

This pull request migrates PHP 8.1.32 to use the wasixcc toolchain and adds sendmail support through an external package dependency, matching the changes previously implemented in PR #11. The PR simplifies the build process by removing custom Rust-based sendmail implementation and adopting standard WASI tooling.

Changes:

• Switched build toolchain from clang/LLVM to wasixcc for WASIX compilation
• Replaced custom wasix_sendmail Rust implementation with external sendmail package dependency
• Removed sendmail_username and sendmail_password INI configuration options
• Updated Wasmer configuration to use --volume syntax instead of deprecated --mapdir
• Consolidated GitHub Actions workflow from separate 32-bit and 64-bit jobs into a single matrix-based job
• Removed SMTP-related secrets and environment variables from CI workflows

The SYSROOT environment variable is being exported but appears to be unused. The wasixcc toolchain (installed via the wasix-org/wasixcc action) manages its own sysroot internally, and the wasix-configure-eh.sh script no longer references this variable. Consider removing this line to avoid confusion.

Suggested change

export SYSROOT=$(pwd)/sysroot/wasix-sysroot-eh/sysroot

There's a double space after --with-imagick on this line. While this typically doesn't cause issues with shell argument parsing, it's inconsistent with the formatting of other configure options. Consider removing the extra space for consistency.

The bash dependency uses an exact version match ("=1.0.25") while the sendmail dependency uses a caret version range ("0.1.5", implicitly "^0.1.5"). This inconsistency could lead to different update behaviors. Consider using consistent version constraints across dependencies - either both exact matches or both ranges - unless there's a specific reason for the difference.

Suggested change

	"sendmail/sendmail" = "0.1.5"
	"sendmail/sendmail" = "=0.1.5"
