refactor(terminology): workplan-first state hub resolver internals (CUST-WP-0055 T05)

Rename open-workplan digest helpers, expose open_workplans alongside legacy
open_workstreams in daily triage digests, and update custodian runtime prompt
prose while preserving wire-compat API paths and query params.
