Introduce JSON-RPC 2.0 handling and a minimal stdio framing server. Adds ApiEndpoints/JsonRpc2 and JsonRpc2Dispatcher to parse and dispatch JSON-RPC requests, and StdioServer to handle Content-Length framed stdio messages. Adds McpToolsList.json (tools list resource) and wires JsonRpc2 into ResourceServer.
Program.cs: add --stdio-jsonrpc2 mode to run the stdio server, and integrate dispatcher usage (with timeout and TODO placeholders for tools/call). ResourceServer: register JsonRpc2 endpoint, change fallback handling to 404 via ServeResource(), and make several resource helper methods static/public for reuse. Update csproj to include new source files and embed the McpToolsList.json resource.
Contains basic implementation and scaffolding; tool-call handling is left as TODO.
Refactored all API endpoint classes from the ResourceTools namespace to the ApiEndpoints namespace for improved clarity and organization. Updated all references in ResourceServer to use the new namespace.
Added null checks for the 'path' parameter in CanHandle methods across all API endpoint classes to prevent potential NullReferenceExceptions. Also made the _apis list in ResourceServer readonly and updated a comment for clarity.
Updated the IApiEndpoint interface and all implementing endpoints to change the CanHandle method signature to accept both HttpListenerContext and path. This enables more advanced routing decisions based on the full HTTP request context. ResourceServer and all endpoint usages have been updated accordingly.
Replaces the custom ICompatibleLogger and TraceLogger with log4net for logging, introducing LoggingBootstrap for environment-aware log4net initialization. Refactors all resource tools to use IApiEndpoint and moves them to the ApiEndpoints namespace. Updates project references, configuration, and adds a log4net.config for consistent logging setup.
