* test(mcp): add comprehensive unit tests for MCP manager and helpers
Add 36 unit tests covering:
- InMemoryMcpClient: tool/resource registration, listing, calling, error cases
- McpManager: start_all (ready/failed/cancelled), list_tools with filters, call_tool,
call_qualified_tool, unregister, stop, list_resources, read_resource, sandbox state
- Tool filter: allow/deny semantics, deny-overrides-allow
- Helper functions: sanitize_component, qualify_tool_name, parse_qualified_tool_name,
parse_server_from_uri
- JsonRpcError: code correctness, envelope formatting
- Serialization: McpServerConfig defaults, McpStartupStatus snake_case
* style: fix cargo fmt formatting
* fix(mcp): preserve truncated qualified tool calls
