Allow/Deny resources list

[manusa]

Description

As a user/mcp admin, I want to be able provide a list of allowed or denied resources, so that I can control and block access to a given set of Kubernetes resources.

Requires #131
Relates to #129

[manusa]

# A list of denied Kubernetes resources in Group/Version/Kind format.
# If a resource is in this list, your MCP server should deny all operations
# on that resource type across all namespaces.
[[denied_resources]]

Would this format make sense to you?.
