reconcileRegistryDrift only healed remote/cloud v1 routes. A v1 global
mode:'ssh' route (host, no url) written by Settings after the one-shot
migration had no registry identity: resolvedConnectionId returned null,
primary stayed 'local', and every launch re-homed the window onto a
fresh local backend. Because the heal skipped SSH entirely, the two
config files re-drifted after every update relaunch instead of
converging once.
Normalize the v1 SSH descriptor into a v2 kind:'ssh' entry (via the
same validated normalizeConnectionInput path the editor uses) and align
primary/lastUsed, with the same narrow-heal rules as remote: already-
registered targets and deliberate primary picks are left alone, and
unusable hosts never touch the registry.
