Pull request overview

This PR adds an AI-assisted safety/risk assessment pipeline for journal entries and introduces a “streak freeze / streak restore” mechanic to the points system, while also making weekly compilation stats selection and AI endpoint handling more robust.

Changes:

• Add local + Worker-refined risk assessment (riskScore/riskLevel) and show supportive/crisis UI after entry submission.
• Add streak freezes/restores with shop purchase flow and cloud-sync persistence.
• Improve weekly projector stats selection (prefer latest delivered weekly package) and harden AI endpoint URL normalization/error details.
