Phase 3: Engine core and variable language

New Issue

Triggers, filters, restrictions, effect lists and queues, $(…) variable language, run traces and replay, migrate existing behaviour onto the engine.

Plan: https://git.subcult.tv/subculture-collective/overlaid/src/branch/main/docs/superpowers/plans/2026-10-05-multiplatform-parity-roadmap.md

October 13: planned; no implementation or runtime acceptance is claimed. Split the tracking scope into a bounded implementation plan before starting. Dependencies and exit criteria remain in the canonical roadmap.
