refactor: use parse-duration library for timeout parsing

Replace the janky hand-rolled duration regex with the well-tested
parse-duration library. This supports more formats including:
- Compound expressions: '1h30m', '1hr 20mins'
- All common units: ms, s, m, h, d, w
- Plain numbers as milliseconds
