Wire Executor Dependencies into IoC Container

Part of #7435 — Multi-Language Hook Support

User Story

As a developer extending the hook system, I want language executors to have their tool CLI dependencies (python.Cli, node.Cli, etc.) properly injected so the system is testable and follows azd's IoC patterns.

Solution Approach

Modify cmd/container.go. The existing python.Cli is already registered as a singleton:

container.MustRegisterSingleton(python.NewCli)

Two options (choose per existing patterns):

Option A (Preferred): Register a PythonExecutorFactory singleton:

container.MustRegisterSingleton(func(pythonCli *python.Cli, commandRunner exec.CommandRunner, console input.Console) *language.PythonExecutorFactory {
    return language.NewPythonExecutorFactory(pythonCli, commandRunner, console)
})

Option B: Construct on-demand in HooksRunner.GetScriptExecutor() using HooksRunner's existing serviceLocator ioc.ServiceLocator.

Update HooksRunner constructor if needed to accept python.Cli or ServiceLocator.

Files: cmd/container.go (MODIFY), possibly pkg/ext/hooks_runner.go (MODIFY)

Acceptance Criteria

• Python executor can be constructed in HooksRunner.GetScriptExecutor()
• No import cycles introduced
• Follows existing IoC patterns from cmd/container.go
• Tests can inject mocks without the IoC container
