docs: remove CrewAI from supported frameworks (#1059)

CrewAI is not implemented as a framework option in the CLI — it does not
exist in SDKFrameworkSchema, has no template assets, and is not in the
SDK_MODEL_PROVIDER_MATRIX. Remove it from README and docs/frameworks.md
to match the actual CLI capabilities.

Constraint: Only frameworks in src/schema/constants.ts SDKFrameworkSchema are valid
Rejected: Mark CrewAI as "BYO only" | no special BYO treatment exists for it
Confidence: high
Scope-risk: narrow

 ## Protocol Compatibility
 
 Not all frameworks support all protocol modes. MCP protocol is a standalone tool server with no framework.
