Remove unused files from repository

- Delete unused libtcc1.a.macos-aarch64 archive (never referenced, ARM64 doesn't need x64 compiler runtime)
- Remove misctools/publish-examples.js (references non-existent examples/ directory)
- Remove misctools/headers-cleaner.js (no references in codebase or build scripts)

The libtcc1.a.macos-aarch64 file was never used because:
- FFI code only compiles libtcc1.c on x64 platforms (Environment.isX64 check)
- ARM64 has native 64-bit operations and doesn't need these compiler runtime functions
- No equivalent files exist for other platforms

The misctools scripts were last modified in 2022 and are no longer used.
