/**
 * 黑板 [663]③ — CC 2.1.202+ config key `workflowSizeGuideline`: an ADVISORY size guideline for
 * LLM-authored workflows (small/medium/large/unrestricted), injected into the Workflow tool's
 * prompt/description. It is guidance, NOT a cap — the hard ceiling stays `WorkflowLimits.maxAgents`.
 *
 * CC 2.1.206 anchors (claude-cli-2.1.206.pretty.js, all verbatim ports):
 * - `cbd = ["unrestricted", "small", "medium", "large"]` + `Tho = { small: 5, medium: 15, large: 50 }` (:17547695)
 * - `Hst` normalize (anything else → "unrestricted") (:17547808)
 * - `Uvs` describe / `qvs` not-a-hard-limit sentence / `dbd` change notice / `Sho` display label /
 *   `ubd` agent cap (:17546855-:17547120)
 * - `Wvs` — the tool-card section; CC appends it to BOTH `prompt()` and `description()` of the
 *   Workflow tool: `return Bvs + Wvs(Tt().workflowSizeGuideline)` (:17593321).
 * - Snapshot semantics: CC memoizes the SESSION-START value (`pbd`) so the card is stable within a
 *   session; a mid-session /config change reaches the model via a `workflow_size_guideline_change`
 *   attachment (`fbd`, :19225552) rendered with `dbd`. sema v1 equivalence: the card is built once
 *   per mount (`createRunWorkflowTool`) = per-task snapshot — same stability property.
 *
 * TODO(变更 reminder 面): CC's mid-session change lane (`fbd` — scan the transcript for the last
 * `workflow_size_guideline_change` attachment, compare with the session-start snapshot, emit a new
 * attachment rendered via `dbd`) needs a per-turn attachment channel sema's engine does not thread to
 * this module yet. v1 ships static injection only; {@link workflowSizeGuidelineChangeNotice} (the
 * `dbd` text, verbatim) is exported ready for that lane.
