fix: update MCP tool schemas to conform to JSON Schema draft 2020-12

Updates JSON schema definitions in GenerateActionTool and SearchRestifyDocs:
- Fix additionalProperties to use proper type definition instead of boolean
- Remove trailing commas from JSON schema objects
- Ensures compatibility with Claude Code MCP validation

Resolves: 400 API error "JSON schema is invalid. It must match JSON Schema draft 2020-12"
