Makes generated Windows executables runnable, expands ZASM syntax and x86
instruction support, and adds native compiler publishing and automated releases.

Compiler and CLI

• Fix PE headers and import addresses so generated executables run correctly.
• Add named db declarations, quoted strings, and symbol address resolution.
• Support imported calls such as call [MessageBoxA], preserving legacy aliases.
• Add x86 memory loads and callback returns for Win32 applications.
• Add run to compile and execute a source file, returning its exit code.
• Prevent execution after failed compilation.

Builds and releases

• Publish Native AOT versions of both zero.exe and zcc.exe, including samples.
• Share version metadata across projects with CI/CD overrides.
• Automatically increment versions after merged pull requests.
• Create tags and GitHub Releases with packaged Windows binaries on master merges.
• Validate every ZASM sample during builds and through automatic unit-test discovery.

Samples and organization

• Add console, arithmetic, string concatenation, named-data, MessageBox,
  and Win32 controls examples.
• Add tutorials, build instructions, and future architecture design notes.
• Organize PE code, x86 definitions, parsing helpers, and diagnostics.

Validation

• All 71 tests pass.
• All nine samples compile.
• Verified native compiler execution and legacy import compatibility.
• Visually verified the Win32 window and button behavior.
