- Re-enable macOS x64 CI builds using macos-15-intel runner
- Remove generic node-pty dependency in favor of platform-specific @lydell/node-pty-* packages
- Add ripgrep binary pruning for platform-specific builds to reduce VSIX size
- Add Windows workaround to remove npm junction self-references during packaging
