Cut a coordinated release

Ship v1.1.0 across all four surfaces using a staggered plan: API + web first, then desktop, then mobile. Document the compatibility matrix in `notes.md` (API v1.0 supports clients ≥ 1.0; API v1.1 supports clients ≥ 1.0). Roll back ONE surface as a fire drill and confirm the others still work.
