Adds three end-to-end tests for the 22b.3 mono pass, each with a matching one-property fixture under examples/. Defends mono-pass invariants 3, 4, and 6 from docs/specs/2026-05-09-22-typeclasses.md at the binary level (stdout-asserting, not AST-asserting): - coherence_two_instances_pick_correct_body_at_runtime — class R with instances at Int and Bool, both reachable from one main. Stdout `11\n22` proves both mono fns are synthesised AND each call site picks the matching body (no collapse). - class_default_method_runs_and_prints_default_value — empty instance body + class-level `default` clause must lower, link, and print the default value (`99`). Promotes the existing synthesise_mono_fn unit test to a binary-level guarantee. - cross_module_class_method_runs_and_prints_correct_value — class+instance in module A, called from module B's main. The qualified-name rewrite + cross-module synth-def placement was AST-tested in 22b.3.6; this pins down the emit-and-link path. All 18 typeclass_22b3 tests pass; full workspace green; 3 bench gates 0/0/0.
