/**
 * Base class for shell command execution with plugin support.
 *
 * Provides a fluent API for building shell commands with indentation support.
 * Uses a plugin system that merges multiple classes into a single instance
 * using the class-merger utility.
 *
 * **Plugin System**: The `_create()` method uses class merging to combine
 * BaseCommando with plugin classes, creating a single instance with methods
 * from all merged classes.
 *
 * **Command Building**: Commands are built using the CommandBuilder, which
 * supports indentation and newline handling. The builder accumulates commands
 * until `execute()` is called.
 *
 * **Note**: The `builder` field is marked readonly but is actually set via
 * `@ts-ignore` in `_create()`. This is a type safety issue.
