* fix(renderer): host writes route only through the strict owner, and twin projections stay on their host (review-5 #2#9#11)
A selected ssh: host that two paired servers proxy now resolves ambiguous at the one
selected-host resolver, so no caller can fall back to this app's own SSH connection.
File Explorer and SSH mutation expectations derive the full {endpoint, place} pair from
resolveOwner, so a server folder's nested SSH target stays the write's host. A local
lineage write projects onto its own host's rows only. The id-only store-write ratchet
now also covers persistence repo-row lookups by id alone (review-5 #10's shape).
* fix(ratchet): the id-only lookup scan also sees optional chaining and destructured ids
* fix(renderer): an unstamped folder keeps reading its host from its repos; editor focus fallback left for a follow-up
* docs(renderer): the File Explorer owner comment names its folder fallback
