[New Feature] Automation and workflow engine

Shipped. Commit dd7a16fc deployed to dev / support / fort-smith-live.

What landed:

• AutomationDispatcher — third EventBus listener after PublicEventEmitter and WebhookDispatcher. Subscribes to user.registered, forum.thread.created, forum.reply.posted, marketplace.listing.created, report.created, moderation.action.taken.
• Conditions — 13 ops (equals/not_equals/gt/lt/gte/lte/in/not_in/contains/starts_with/ends_with/is_set/is_empty), dotted-path field lookup, AND across rows.
• Actions (v1) — send_dm, add_badge, award_credits, move_thread. Cheap ones run inline on the request, slow ones queue to automation_runs for the per-minute worker. Template-interpolated params ({{data.author.id}}).
• Admin UI at /admin/automation with CRUD, toggle, and run history (super-admin only).
• Schema — automation_rules + automation_runs per-tenant (FOR UPDATE SKIP LOCKED queue claim).
• Cron 31 — bin/process-automation-queue.php wired via scripts/cron.d/mobieus-platform-admin-automation-queue (fan-out across active tenants).

Smoke test: worker runs cleanly on all 3 tenants with 0 rules (exit 0, “claimed 0”). Action handlers are recursion-safe — they never emit EventBus events.

Now you can build “welcome DM on join” / “feature thread on report” / “badge on first post” from the admin without code changes.
