Pull request overview

This PR adds “snapshot release” support across the core releaser/project logic and the GitHub Action wrapper, enabling timestamp-suffixed prerelease versions (e.g., -snapshot.YYYYMMDDHHMMSS) and a workflow that publishes then reverts version changes.

Changes:

• Add snapshot prerelease identifiers (with timestamp) and supporting semver bump behavior in core utilities/project version calculation.
• Add skipChangelog support to bumps and introduce a revert() step to undo version file updates after publishing (useful for snapshot publishing).
• Extend the GitHub Action to accept a bump-snapshot input and add a runSnapshotAction() flow.
