feat(homecore-automation/p1): ADR-129 automation engine + MiniJinja templates (34 tests pass)
Scaffolds `v2/crates/homecore-automation` per ADR-129 HOMECORE-AUTO: - Automation struct with RunMode (single/restart/queued/parallel/ignore_first) - Trigger enum: State, NumericState, Time, Event + EvaluateTrigger trait - Condition enum: State, NumericState, Template, And, Or, Not + async evaluate - Action enum: ServiceCall, Delay, Scene, WaitForTrigger, Choose + async execute - TemplateEnvironment: MiniJinja 2.x with HA globals states(), state_attr(), is_state(), now() - AutomationEngine: subscribes to state-machine broadcast, evaluates triggers, runs action tasks 34 unit tests pass (0 failed). MiniJinja filter coverage: states, state_attr, is_state, now (P1 set). Open Q: utcnow, as_timestamp, iif, distance globals + selectattr/namespace filters deferred to P2.
