/**
 * Injection Engine — evaluator.
 *
 * Pattern: Pure function. Stateless.
 * Role:    Internal helper. Called once per iteration by the
 *          InjectionEngine subflow's compose stage. Slot subflows
 *          read the `active` array and filter by their slot target.
 * Emits:   N/A. Caller (the subflow) emits
 *          `agentfootprint.context.evaluated`.
 *
 * Behavior per trigger kind:
 *   • `always`             → always active.
 *   • `rule`               → predicate runs against `ctx`. Errors are
 *                            caught + reported in `skipped`; never
 *                            propagate. Run never crashes.
 *   • `on-tool-return`     → active when `ctx.lastToolResult.toolName`
 *                            matches `trigger.toolName` (string equal
 *                            or regex test).
 *   • `llm-activated`      → active when the Injection's `id` is in
 *                            `ctx.activatedInjectionIds` (the LLM
 *                            previously called `viaToolName(<id>)`).
