v0.3.1

Compatibility: allow timmcleod/agent-workflows ^0.10 (hardening release). No dashboard changes.

Hosts upgrading core should run php artisan migrate — core v0.10 ships additive migrations (hot-path indexes, foreign key removal, and a catch-up for the v0.8 → v0.9 timeout_at gap). See the core v0.10.0 release notes for the breaking-change list.
