Pull request overview

Adds a safeguard to detect when the Godot version recorded in the game’s persisted configuration has drifted from the Godot version implied by the local project.godot, warning or stopping a ship to prevent publishing builds with an incompatible engine version.

Changes:

• Introduces detectGodotVersion() (null-safe wrapper) and getGodotVersionDrift() (major/minor drift detection) in the Godot utilities.
• Adds pre-ship drift checking when --gameEngineVersion is not explicitly provided: warn on minor drift, error on major drift with actionable CLI guidance.
• Adds unit tests covering version detection and drift classification.
