Breaking

Removed raw mode from WebFetchTool — the raw parameter is no longer accepted; content-type is now auto-detected and dispatched to the appropriate handler
WebFetchTool constructor now accepts an optional FetchRegistry as second parameter
WebToolsPackage constructor now accepts an optional FetchRegistry as third parameter

Features

Content-type handler dispatch — WebFetchTool now auto-detects response content type and routes to a matching handler via FetchRegistry
New content handlers: HtmlHandler, JsonHandler, XmlHandler, CsvHandler, MarkdownHandler, PlainTextHandler, GenericTextHandler
JSON pretty-printing — application/json responses are parsed and re-serialized with 2-space indentation for readability
Automatic support for XML, CSV, and Markdown responses (returned as-is)
FetchRegistry with lazy initialization and custom handler support — register your own handlers that take priority over built-in defaults
New public exports: ContentHandlerRegistry (alias for FetchRegistry), all content handler classes, and the ContentHandler interface type

Updated @johannes.latzel/llm-chat dependency from ^0.5.0 to ^0.6.0
truncate function refactored from web-fetch.ts into lib/content-handlers/util.ts with improved boundary detection (paragraph → sentence → word → hard cut)
Config classes (WebSearchConfiguration, WebFetchConfiguration) now have JSDoc annotations on all properties
All docs files rewritten: README, architecture.md, configuration.md, quickstart.md, usage.md
New test suite for content handlers and FetchRegistry
Various dependency bumps (@typescript-eslint/* 8.61.1→8.62.0, nanoid 3.3.12→3.3.15, semver 7.8.4→7.8.5, @types/node 22.19.21→22.20.0)
README badge upgraded to NodeI co-branded shield
