snapclass 0.1.2

What's Changed

• Add snapclass lifecycle hooks for migration/live-state setup:
  • __snapclass_ready__(self, *, snapshot) after snapshot attachment and setup.
  • __snapclass_loaded__(self, *, snapshot, path) after file data is applied.
• Suppress autosave/reload behavior while lifecycle hooks run.
• Wrap lifecycle hook failures in SnapclassError with hook name and path context when available.
• Document the hook contract in the packaged snapclass fluency skill.

Migration Notes

• Hooks are intended for transient/live state setup and post-load rebuilds.
• Hook code should be idempotent and should not mutate fields used by the snapshot pattern.
• Sidecars may be read inside hooks; sidecar writes should happen after hooks return.
