sync: delete-guard exclusion + retention
sync: the 08-23 fix day — registry hardening, per-poll isolation, smarter backups Regenerated from the repo docs by tools/sync_wiki.sh. Nine pages updated. The substantive ones: - Backup: two new sections (Space — why a 1.4 GB backup now costs ~65 MB; and A missing destination is a failure, not a thing to create) - Performance: the SelectorTile row corrected, plus a note recording that an earlier "out of the top six" claim was measured on an unlike scene and does not hold — like-for-like it is ~4% - Multi-Mod: the schema contract section (advisory, never a gate) - Testing: 501 -> 589 unit tests - Changelog / Review-Backlog: the day's fixes and the surviving residue
