Upgrade to 1.0.0-rc650

Concerns: pushword/version

Version: activity journal (who changed what, when)

The version package now records every versionable action (create / update / restore) into a queryable activity log, surfaced as a read-only admin journal ordered newest-first with filters (type, editor, action, host). Each row links to the entity's edit screen (when it still exists) and to the side-by-side diff. The on-disk snapshots are unchanged — this adds a denormalized index on top of them.

• New table: version_log (written via a direct insert when the action happens; the editor is captured for authenticated edits, left empty for flat sync / CLI).
• New command: pw:version:log:clear empties the journal, or --days=N prunes entries older than N days. Snapshots on disk are untouched.

Migration steps

1. composer update
2. php bin/console doctrine:schema:update --force (required — adds the version_log table the journal reads/writes)
3. php bin/console cache:clear

No breaking changes: the journal starts empty and fills as pages/snippets are edited (there is no backfill of pre-upgrade history).
