Canonical file path
Given an absolute Unix-style file path, return its canonical form. In the path, `.` means the current directory, `..` means the parent directory (and is a no-op at the root), and multiple consecutive slashes are treated as a single slash. The canonical path must start with a single `/`, must not have a trailing slash (except for the root `/`), and must not contain any `.` or `..` components or empty segments.

["/home//foo/"]out"/home/foo"What a strong answer looks like
State your approach and its time/space complexity out loud before you optimize. Handle the edge cases (empty input, duplicates, overflow), and say why you chose this over the brute force. Green tests are the floor, not the grade.
