Refactor to extract common command execution logic

Extracted the common code from ExecuteWithProjectProfile and ExecuteWithExecutableProfile into a new ExecuteCommand method. This method handles:
- Applying launch settings to the command
- Applying environment variables from command line
- Sending telemetry
- Setting up Ctrl-C handler
- Executing the command

This reduces code duplication and makes the execution flow clearer.
