a987a3a248The constructor guarded its unwritable-directory case with the global `\RuntimeException`, the only throw in `src/` still outside `Mcp\Exception\ExceptionInterface`. A consumer wrapping server setup in a `catch (ExceptionInterface)` missed it and got an unhandled SPL exception on a misconfigured session directory instead. `Mcp\Exception\RuntimeException` extends `\RuntimeException`, so this is additive: existing `catch (\RuntimeException)` blocks keep working. The constructor had no test coverage at all, so this adds one for the throw plus the directory-creation and write/read paths around it.
