- Single source of truth for the active user via data/current-user.ts;
layout pushes authStore.user.id into it on every auth state change.
- Dexie creating-hook auto-stamps userId from getEffectiveUserId(); the
updating-hook strips userId from modifications so records are
effectively user-immutable after creation.
- BaseRecord gains an optional userId so module types inherit it without
per-module declarations. All hardcoded 'guest'/'local' fallbacks in
module type-converters and session timer stores are deleted; the dead
userId field is removed from the public view types where it was
unused (Task, Conversation, Template, Deck, Plant, Contact, etc.).
- New guest-migration.ts: on first authenticated session, walks every
sync-tracked table, deletes guest-owned records and re-adds them so
the creating-hook re-stamps with the real user id and produces fresh
insert pending-changes with the full payload. Stale guest pending-
changes are cleared up-front.
- Drive-by: root onMount now returns its cleanup synchronously; the
previous async form silently dropped the cleanup callback.
