docs: state local MCP key requirements exactly

[MagMueller]

Clarifies that direct local MCP browser tools do not need an LLM key. Content extraction uses an OpenAI-compatible key. The autonomous agent tool uses that route by default and also supports configured AWS Bedrock credentials. Removes the unsupported Anthropic-key fallback claim.

Validated the absent-OpenAI/Anthropic-only error and the Bedrock routing branch without provider calls. The Bedrock constructor was replaced by a sentinel for routing only; AWS authentication and inference were not tested. Mint found no broken links, docs.json parsed, and git diff --check passed. The generated LLM-readable mirror was synchronized.

Summary by cubic

Clarifies the local MCP server's LLM key requirements so users don't set up unused keys. Direct browser automation tools like navigate, click, type, page state, HTML, and screenshot work without an LLM key; content extraction requires an OpenAI-compatible key, and the default autonomous agent route also uses OpenAI-compatible by default or AWS Bedrock when configured. Removes the unsupported Anthropic-key fallback from environment variables and troubleshooting.

^{Written for commit b068ec1. Summary will update on new commits.}
