fix: migrate from @arcjet/duration to parse-duration library

- Replace @arcjet/duration with parse-duration for better Go duration format support
- Fix workspace timeout validation to handle milliseconds instead of seconds
- Add regex validation to reject bare numbers without units
- Update parseGoDurationToMs to handle null returns properly
- All 108 tests passing, mixed-unit duration bug completely resolved

The @arcjet/duration library had usage warnings and parsing issues with
mixed-unit durations like '1h30m' being incorrectly parsed as '1m'.
parse-duration is better maintained (367 dependents, 285k weekly downloads),
has zero dependencies, and provides perfect Go duration format compatibility.
