Custom exceptions for Zen MCP tools.

|
|
These exceptions allow tools to signal protocol-level errors that should be surfaced
|
|
to MCP clients using the `isError` flag on `CallToolResult`. Raising one of these
|
|
exceptions ensures the low-level server adapter marks the result as an error while
|
|
preserving the structured payload we pass through the exception message.
