/**
 * Central live healing for leaked reasoning markup in the visible text channel.
 *
 * Some providers emit their canonical reasoning idioms (` ```thinking `,
 * `<think>`, Gemma/Harmony channels, …) into the *visible* text stream instead
 * of a structured thinking part. {@link wrapLeakedThinkingStream} re-projects a
 * provider stream into a fresh {@link AssistantMessageEventStream}, splitting the
 * leaked fences out into proper `thinking` blocks *live* as deltas arrive.
 *
 * Applied to every provider stream *except* official first-party endpoints
 * (the official Anthropic API and the official OpenAI / OpenAI-Codex endpoints),
 * which return structured thinking and never leak — `healLeakedThinking` in
 * `../stream.ts` gates the wrap so the healer cannot misfire on legitimate
 * fenced content those models emit as visible text.
 *
 * The healing is idempotent: a second pass over already-clean text finds no
 * fences, so wrapping a provider that already heals (or wrapping twice) is a
 * harmless pass-through. Signatures are load-bearing for Google/Gemini/Vertex
 * thought round-tripping, so text sub-blocks carry the source `textSignature`,
 * forwarded thinking blocks their `thinkingSignature`, and forwarded tool calls
 * their `thoughtSignature`.
 *
 * Modeled on {@link wrapInbandToolStream} / `InbandStreamProjector` in
 * `../dialect/owned-stream.ts`, minus all in-band tool-call grammar: tool-call
 * events are forwarded verbatim.
