mcp(tests): Add integration tests for resources via real MCP protocol

[tony]

Context

tests/mcp/test_resources.py uses a MockMCP class that captures decorated functions and calls them directly. This never exercises FastMCP's URI routing, parameter encoding/decoding, or actual MCP protocol handling.

Problem

The test suite validates that resource functions work correctly, but doesn't validate that:

• Resource URIs are correctly routed by FastMCP
• Parameter values (especially with special chars) are properly encoded/decoded
• JSON responses are properly formatted for MCP clients
• Integration with the actual MCP server transport works

Proposed Solution

Add integration tests that use fastmcp.Client (or equivalent) to make real read_resource() calls against the registered MCP server, exercising the full FastMCP protocol stack.

Fixed in commit 35e43eb — added integration tests using FastMCP Client(mcp) for in-process protocol testing.
