/**
* Leaf↔Root Link — v0.8.0 MVP
*
* Two halves in one class, ship together in every install:
*
* ROOT half — REST endpoint /sa-orch/v1/root/assignments
* Returns Fluent Boards tasks where the authenticated user is
* an assignee (via fbs_relations object_type='task_assignee').
* Auth: WP application password (Basic auth) or session nonce.
*
* LEAF half — Admin page (SA-Orchestration → Remote Roots)
* Stores ONE remote root config in wp_options (URL + app
* password). Manual "Fetch Now" button calls the configured
* root's /assignments endpoint and renders results in a
* table on the same admin page.
*
* MVP scope (locked):
* - One root per leaf (multi-root deferred to post-MVP)
* - No new tables — single wp_option for config
* - Manual fetch only; no cadence, heartbeat, or cron
* - No Fluent Support ticket creation; just list assignments on screen
* - No outbound curated updates; bidirectional sync is post-MVP
*
* The closed loop: developer self-assigns on Fluent Boards on the dev root
* → leaf admin clicks "Fetch Now" → assignment appears in the leaf's
* Remote Roots admin page.
*
* Doctrine: leaf-initiated, always up; the dev root never reaches into
* the leaf. Per Board #40 invariants.
