feat(atoms, react): add single-signal wrapping to injectMappedSignal#337
Conversation
…dSignal Add support for wrapping a single Signal directly with injectMappedSignal, creating a thin wrapper that keeps the inner signal reference up-to-date and triggers changes when the reference changes. The MappedSignal's state is identical to the wrapped signal's state, and events pass through directly. - Add F (Forwarding) property to MappedSignal for single-wrapped signal - Implement single-signal mode in set/send/r/u methods - Add function overloads to injectMappedSignal for both signatures - Add 14 comprehensive tests for single-signal wrapping functionality - Ensure all 445 existing tests continue to pass

Description
Added support for wrapping a single Signal directly with
injectMappedSignal. Previously,injectMappedSignalonly accepted an object of signals. Now it accepts either aSignalMap(object) or a singleSignal, creating a thin wrapper that keeps the inner signal reference up-to-date.When wrapping a single signal, the MappedSignal's state is identical to the wrapped signal's state (not wrapped in an object), and all events pass through directly without key prefixes. This is useful for composing signals while maintaining a consistent reference to the wrapped signal across atom reevaluations.
Changes
F(Forwarding) property for single-wrapped signals and single-signal mode handling inset(),send(),r(), andu()methodsStateOfandEventsOftype helpers correctly extracting types for both approachesAll existing tests (445) continue to pass.
