Cross-Platform Path Handling

CRITICAL: This extension runs on Windows, macOS, and Linux. Path bugs are the #1 source of issues.

Core Rules

Rule 1: Never Concatenate Paths with /

// ❌ WRONG: POSIX-style path concatenation
const envPath = homeDir + '/.venv/bin/python';

// ✅ RIGHT: Use path.join()
const envPath = path.join(homeDir, '.venv', 'bin', 'python');

Rule 2: Use path.resolve() for Comparisons, Not path.normalize()
