When `mino run` is invoked interactively with no layers, image, or config, prompt the user to select development tool layers via a multiselect picker. After selection, offer to save the choice to local .mino.toml or global config.

CI, IDE plugins, and parent processes can set MINO_LAYERS=rust,typescript to specify layers without a config file or --layers flag every invocation. Precedence: CLI --layers > --image > MINO_LAYERS env > config layers. Manual env read avoids clap conflict with --image (env= attribute would error when MINO_LAYERS is set and --image is passed).
