Deluan ae93e555c9 feat: refactor MCP agent to support native and WASM implementations
Refactored the MCPAgent to delegate core functionality to separate implementations for native process and WASM execution.

Introduced an `mcpImplementation` interface (`MCPNative`, `MCPWasm`) to abstract the underlying execution method. The main `MCPAgent` now holds an instance of this interface, selected by the `mcpConstructor` based on the `McpServerPath` (native executable or `.wasm` file).

Shared Wazero resources (runtime, cache, WASI, host functions) are now initialized once in the constructor and passed to the `MCPWasm` implementation, improving resource management and potentially startup performance for WASM modules.

Updated tests (`mcp_agent_test.go`) to use a new testing constructor (`NewAgentForTesting`) which injects a mock client into the appropriate implementation. Assertions were adjusted to reflect the refactored error handling and structure. Also updated the `McpServerPath` to use a relative path.
