- Add a header link on each tool pointing to the other.
- Add a Send to Scope Lock button on Workshop clusters that carry a
candidate solution tag. Writes the item to a shared localStorage
queue (sde_scope_handoff_v1).
- Scope Lock drains that queue on load and adds each item to the
Scope Boundary Board as unsorted, deduping by a deterministic id so
a repeat send never creates a duplicate.
- No backend needed: both tools already share the same browser origin.
- Verified with a jsdom test covering send, drain, reload, and
re-send-after-reset.
- Update README and CHANGELOG.
