 * @property entryPoints - Map of subpath → entry source file. The TCK
 *   reads each entry, follows its relative re-exports recursively, and
 *   snapshots the resulting surface text. Empty-string subpaths label
 *   the root entry; everything else is rendered with its key (e.g.

/**
 * Snapshot-based public-API stability check. Walks each entry's source
 * file plus everything it re-exports through relative imports, and
 * compares the concatenated text against a committed Vitest snapshot.
 *
 * Catches accidental rename / removal / signature drift on the public
 * surface before a build merges. Any change that affects re-exports
 * shows up as a snapshot diff in the PR; reviewers either accept the
 * change (update the snapshot deliberately) or push back.
 *
 * The TCK reads source (`.ts`) rather than built declarations so it
 * doesn't need a prior `pnpm build`. It follows `from "./relative.js"`
 * re-exports transitively; non-relative paths (other packages, `node:`)
 * stop the walk — drift in another package's surface is that package's
 * stability TCK to catch.
 *
 * @example
 * ```ts
 * import path from "node:path";
 * import { runStabilityTck } from "@rotorsoft/act-tck";
 *
 * runStabilityTck({
 *   name: "@rotorsoft/act-http",
 *   entryPoints: {
 *     "/api": path.resolve("src/api/index.ts"),
 *     "/webhook": path.resolve("src/webhook/index.ts"),
 *     "/sse": path.resolve("src/sse/index.ts"),
 *     "/receiver": path.resolve("src/receiver/index.ts"),
 *   },
 * });
 * ```
 *
 * @param options - See {@link StabilityTckOptions}.
