Build a Chrome extension called "JSON Pretty Printer" that detects raw JSON responses (Content-Type: application/json or pages whose body parses as valid JSON) and replaces the rendering with a collapsible, syntax-highlighted tree with line numbers, copy-path-to-clipboard on each node, and a search bar. Provide a toolbar toggle to fall back to raw JSON. Permissions: activeTab, storage. Host permissions: <all_urls>. Manifest V3 with content script and document_start run timing.
