feat: simplify selection of project creation

[Soner (shyim)]

[Copilot]

Pull request overview

This PR introduces usage tracking and a more guided interactive flow for project create, while also improving shutdown handling and Docker-based Composer behavior.

Changes:

• Add a new internal/tracking package that resolves a stable user ID and emits UDP tracking events, plus accompanying tests.
• Update project create to use a simplified version selection UI (grouped selection) and optionally hide “advanced” configuration.
• Add signal-aware root context cancellation and introduce a Docker mountability helper used during Docker-based Composer installs.
