This PR updates the project to use modern Node.js import patterns and the latest type definitions.

Changes Made

Updated @types/node dependency:

• Upgraded from ^10.17.60 to ^24.5.0 to use the latest Node.js type definitions

Modernized import statements:

• Added node: prefix to all Node.js built-in module imports (21 total imports updated)
• Updated imports for: buffer, events, fs, path, stream, url, and util modules
• This follows the modern Node.js best practice of explicitly identifying built-in modules

Fixed type compatibility issues:

• Updated function signatures to use proper BufferEncoding types instead of generic strings
• Fixed Buffer.from() type casting for ArrayBuffer/ArrayBufferView parameters
• Added optional chaining for process.getuid()/process.getgid() calls to handle platforms where these methods are undefined
• Enhanced dataToBuffer function to properly handle the extended encoding type that includes 'buffer'
• Fixed type casting in directory traversal operations

Benefits

• Modern standards: Uses current Node.js import conventions with explicit node: prefixes
• Better type safety: Leverages the latest Node.js type definitions for improved development experience
• Future-proof: Ensures compatibility with modern Node.js tooling and bundlers
• No breaking changes: All existing functionality is preserved with full test coverage

All builds pass, formatting is correct, and the complete test suite (888 tests) runs successfully with no regressions.

Fixes #1185.
