/**
 * Shared reasoning-effort defaults for the SSH TUI.
 *
 * OpenCode / third-party (llm-pi-ai) routes carry no adapter-level reasoning
 * default. Without an explicit effort the model streams its thinking as plain
 * `text` chunks instead of `reasoning` blocks, so the TUI never receives the
 * data needed to render the collapsible `思考中` block. This helper picks a
 * supported default so the fold has data to show.
 *
 * `llm-deepseek` is not covered here: its adapter always reports a
 * `defaultEffort`, which the LLM runtime materializes into the request on its
 * own. Since the 0.5.1 STORE compliance trim dropped the bundle patch's
 * `reasoningEffort: max` row override, that adapter default is `high` unless a
 * deployment sets it (or `/effort` picks one, remembered per route).
