@tiptap/extension-youtube 3.14.0

# Notes: TipTap YouTube Extension Verification

## Search Result
`search_known_solution` returned `NO_SAFE_MATCH` for `pkg:npm/%40tiptap/extension-youtube@3.14.0`. No verified public sample existed in the network for this extension. This sample demonstrates the exact module exports, schema definitions, command validation, options configuration, and HTML rendering contracts.

## Naive Model Assumption
A developer or coding model assumes that `@tiptap/extension-youtube` exports individual utility functions such as `isValidYoutubeUrl` or `getEmbedUrlFromYoutubeUrl` as named exports, and that the extension can be loaded independently of TipTap's peer dependencies. Additionally, models often assume that `Youtube` is an inline node or that setting YouTube videos does not validate the URL before inserting content.

## Exact Behavior & Failure Mode
1. **Module Exports**: In the built distribution (`dist/index.js`), only `Youtube` and its default export are provided. Internal helpers like `isValidYoutubeUrl` are not re-exported.
2. **Peer Dependencies**: `@tiptap/extension-youtube` imports from `@tiptap/core` (which in turn requires `@tiptap/pm`). Both must be resolved and present in dependencies.
3. **Node Definition**: `Youtube` is a block-level node (`inline: false`, `group: 'block'`, `draggable: true`) with default dimensions 640x480.
4. **Command Validation**: `setYoutubeVideo` command inspects the `src` attribute against valid YouTube URL patterns. Valid URLs return `true` and dispatch `insertContent`; non-YouTube or invalid URLs return `false` and do not modify the editor.
5. **HTML Rendering**: `renderHTML` transforms standard watch URLs (`youtube.com/watch?v=...`) and short URLs (`youtu.be/...`) into canonical embed URLs (`youtube.com/embed/...` or `youtube-nocookie.com/embed/...`) with query parameters reflecting configured options (`rel`, `controls`, `autoplay`, `loop`, `start`, etc.).

Clean-room public code sample — generation instructions

Write a brand-new, minimal, self-contained code sample in this clean-room directory.
Do not copy, paraphrase, or reference any existing project source. Work only from this spec.

A csx.json manifest scaffold already exists. Do not recreate it from memory. Preserve its case.goal, packages and symbols; fill its empty case.contract with exact assertions and correct its environment, commands and verifierAdapter for the files you generate.

Goal: verify pkg:npm/%40tiptap/extension-youtube@3.14.0
Kind: HOW

Use EXACTLY these public packages and versions:
  - pkg:npm/%40tiptap/extension-youtube@3.14.0

Rules:
  - One focused purpose; the smallest project that proves the goal.
  - Include a contract test (test/contract.*) that runs OFFLINE and exits 0 exactly when the goal behavior works.
  - Pin every dependency with a lockfile so resolution is reproducible.
  - No secrets, credentials, or tokens. No real URLs (only example.com or localhost). No absolute paths.
  - No personal names, emails, company names, or project identifiers of any kind.
  - No binaries and no generated output (node_modules, dist, target, venv, .git, .env).
  - Keep it under 200 files and 256KB packed.
