/**
 * Plane tracker adapter — projects Plane onto the neutral TrackerAdapter
 * contract. Promoted from strategy/plane-app-draft/plane-adapter.draft.js.
 * ============================================================================
 *
 * Mirrors the proven shape of linear.js: ONE auth chokepoint (planeFetch, with
 * X-API-Key), the 6 neutral methods, and a NeutralTicket with `state` (raw
 * name), `stateCategory` (normalized bucket) and `_raw`.
 *
 * Plane specifics that drove the design (verified — see RESEARCH.md):
 *   - Auth: personal access token in header `X-API-Key: <token>`. Self-hosted ⇒
 *     base URL is the TENANT's host (https://<host>/api/v1), NOT api.plane.so.
 *     Both come from env (same posture as linear.js).
 *   - Scoping: every issue is workspace_slug → project_id → id. No global list,
 *     so the adapter is bound to a (workspace, project) via env or per-call ctx.
 *   - States carry a `group` ∈ {backlog, unstarted, started, completed,
 *     cancelled} — the normalization key. NO transition object: you PATCH the
 *     work-item `state` to a target state uuid (like Linear, unlike Jira).
 *   - List endpoints are cursor-paginated:
 *       { results, next_cursor, prev_cursor, count, total_results, ... }
 *     per_page default & max 100; cursor format "value:offset:is_prev".
 *   - Comments are HTML (comment_html), NOT markdown. We wrap plaintext.
 *
 * HONEST TODOs (inline) are Plane-version-specific details not fully confirmable
 * from the public docs without a live instance — kept from the research draft.
