Function relativePath

relativePath(path: string, relative: string): string
Resolves a relative path against a base path and normalizes the result.

If the relative path is absolute, returns it directly. Otherwise, joins the base and relative paths, then normalizes by resolving ".." (parent) and "." (current) directory references.
Parameters
- path: string
  Base path to resolve against
- relative: string
  Relative path to resolve (or absolute path)
Returns string
Normalized resolved path
Example
```
relativePath('/home/user', 'docs/file.txt');
// '/home/user/docs/file.txt'

relativePath('/home/user/project', '../config.json');
// '/home/user/config.json'

relativePath('/home/user', '/etc/hosts');
// '/etc/hosts' (absolute path takes precedence)

relativePath('/a/b/c', '../../d');
// '/a/d'
```
