Keep the salvaged botHandle normalization, but remove the unconditional
hermes alias on remote default profiles: the parser's last-wins map
otherwise retargets a local @hermes handoff by roster order.
Consolidate regression coverage into two invariants for persisted primary
handles, both handoff directions and three-source qualified identity.
Capture real Electron screenshots, durable logs and source receipts;
exercise the reverse live handoff too. Document the repair and bump the
bundled Desktop patch version.
