feat(Cocoon): Implement progress IPC notifications to Mountain

Replace TODO placeholder implementations in the WithProgress API with actual gRPC notifications to Mountain backend. The report() method now sends progress.update notifications, progress start sends progress.start with location/title/cancellable options, and progress complete sends progress.complete.

This enables the Mountain backend to display real-time progress indicators while VS Code extensions execute long-running tasks.

Also fixes shell script shebangs from bash to sh for broader POSIX compatibility.
