docs: update spectrum-ts documentation for v11.1.0

Documentation Update: spectrum-ts v11.1.0

This PR updates documentation for spectrum-ts based on the v11.1.0 release.

Release Notes

New Features

• WhatsApp Business now supports unsending reaction messages. Calling message.unsend() on a reaction sends Meta’s reaction-removal form.

• WhatsApp Business reaction removals now come through as portable unsend content, so apps can handle them the same way across providers. asUnsend is also exported from @spectrum-ts/core/authoring.

Bug Fixes

• WhatsApp Business streams no longer stop when Meta sends a reaction-removal event with an empty emoji. The bad event is mapped or skipped, and later messages keep flowing. ✨

• iMessage streams now skip deterministic “poison” events instead of retrying them forever and blocking everything behind them. Retryable mapping errors still retry, so transient gateway issues can recover normally.

• iMessage contact-share side effects now run only after a message is successfully converted, avoiding false dedupe burns for skipped events.

Improvement

• Docs were refreshed with generated type references and a new iMessage troubleshooting section for cases where Apple delivers text that differs from what the sender sees.

Note

Medium Risk
A six-major-version jump on the docs extraction dependency can change generated types/nav until docs:generate is re-run and reviewed; runtime app risk is low since this is dev-only.

Overview
Bumps the spectrum-ts devDependency from 5.2.0 to 11.1.0 and refreshes pnpm-lock.yaml so doc generation (docs:generate, Vellum/TypeScript extraction) runs against the v11 API surface.

The lockfile shift pulls in @spectrum-ts/*@11.1.0, newer @photon-ai/otel@3.1.0 (optional Undici instrumentation), @photon-ai/advanced-imessage@1.0.0, and @photon-ai/whatsapp-business@0.2.0, while dropping older iMessage paths (@photon-ai/imessage-kit@3.0.0, @parseaple/*). @spectrum-ts/core no longer lists optional Elysia / Express / Hono peers in the resolved tree.
