Function createStonePluginContext

createStonePluginContext(
    context: ConsoleContext,
    command: string,
    reporter: StoneReporter,
    contributions: PluginContributions,
): StonePluginContext
Build the stable StonePluginContext facade handed to a plugin's build hooks.

The facade wraps the CLI's internal ConsoleContext and a shared PluginContributions accumulator, exposing only the small, stable surface plugin authors depend on.
Parameters
- context: ConsoleContext
  The CLI build context.
- command: string
  The command driving the lifecycle (e.g. build, dev).
- reporter: StoneReporter
  The branded reporter for user-facing output.
- contributions: PluginContributions
  The shared accumulator every plugin writes into.
Returns StonePluginContext
The plugin context facade.
