9349f5cb26* feat: add prompt support with typed argument handling - Implement #[prompt], #[prompt_router], and #[prompt_handler] macros - Add automatic JSON schema generation from Rust types for arguments - Support flexible async handler signatures with automatic adaptation - Create PromptRouter for efficient prompt dispatch - Include comprehensive tests and example implementation This enables MCP servers to provide reusable prompt templates that LLMs can discover and invoke with strongly-typed parameters, similar to the existing tool system but optimized for prompt use cases. 🤖 Generated with Claude Code Co-Authored-By: Claude <noreply@anthropic.com> * refactor: unify parameter handling between tools and prompts - Replace Arguments<T> with Parameters<T> for consistent API - Create shared common module for tool/prompt utilities - Modernize async handling with futures::future::BoxFuture - Move cached_schema_for_type to common module for reuse - Update error types from rmcp::Error to rmcp::ErrorData - Add comprehensive trait implementations for parameter extraction 🤖 Generated with Claude Code Co-Authored-By: Claude <noreply@anthropic.com> * refactor: extract Parameters wrapper to shared module and unify trait usage - Move Parameters type from common.rs to dedicated wrapper/parameters.rs module - Unify extractor traits by using FromContextPart for both tools and prompts - Remove duplicate FromToolCallContextPart and FromPromptContextPart traits - Add structured output support to Json wrapper with IntoCallToolResult impl - Improve error messages with more descriptive panic for schema serialization - Update all imports across codebase to use new module path - Clean up trailing whitespace and formatting inconsistencies This consolidates parameter extraction logic and reduces code duplication between tool and prompt handlers while maintaining backward compatibility. * chore: remove committed .egg-info directory and update gitignore * docs: fix documentation formatting
