Remove UpdateConnectionOperation completely as planned for v2.16.0.
This is a breaking change - users should use removeConnection + addConnection
or the new rewireConnection operation instead.
Changes:
- Remove UpdateConnectionOperation type definition
- Remove validateUpdateConnection and applyUpdateConnection methods
- Remove updateConnection cases from validation/apply switches
- Remove updateConnection tests (4 tests)
- Remove UpdateConnectionOperation import from tests
All 137 tests passing.
