fix: cover semver patch suffix parsing (#1110) (thanks @zerone0x)

Strip prerelease (`-beta.1`) and build (`-4`) suffixes from the patch
component before parsing as integer. Previously `2026.1.11-4` parsed to
`patch: 0` because `Int("11-4")` returns nil; now correctly yields
`patch: 11`.

Fixes #1107
