⭐ Signals

@ngrx/signals — real source, 906/906 tests passing, 0 lint errors. No @ngrx/store dependency, audited clean. The first module added the corrected way from the start: its ng-add schematic went straight into the shared modules/schematics package (see Schematics Consolidation) with no per-module copy to migrate away from later, unlike the 8 modules added before that consolidation happened.

Found a real baseUrl/Node-builtin-module naming collision bug (a local module named events, colliding with Node's built-in) while wiring the module up. Not yet covered by the code review audit — store-devtools is now complete; 8 modules (including this one) remain, not yet started.
