fix: preserve prerelease alternatives alongside wildcard ranges

[x0Lazarus]

satisfies('1.2.3-alpha', '* || 1.2.3-alpha') currently returns false, even though the explicit 1.2.3-alpha alternative matches on its own. The range constructor reduces the whole expression to *, which excludes prereleases by default.

Keep one wildcard and the alternatives containing prerelease bounds, preserving their order. Alternatives without prerelease bounds can still be dropped. With includePrerelease: true, the wildcard already admits prereleases, so the expression still reduces to a wildcard.

The regression fixtures cover both alternative orders, repeated wildcards, multiple prerelease alternatives, bounded prerelease ranges, ordinary releases, and rejection of other prereleases. The matching and formatting regressions fail against the original code and pass with this change.

On Windows with Node 24.19.0, npm test --ignore-scripts passes with 100% statement, branch, function and line coverage. npm run lint --ignore-scripts and npm run postlint --ignore-scripts also pass. The full CI platform and Node-version matrix has not been run locally.

This follows the prerelease distinction described in the earlier discussion.
