* fix: use full IP for userId to prevent quota collision - Remove .slice(0, 8) from base64 encoded IP - Each IP now has unique userId (no /16 collision) - Affects: quota tracking, Langfuse tracing * refactor: extract getUserIdFromRequest to shared utility - Create lib/user-id.ts with shared function - Fix misleading 'privacy' comment (base64 is not privacy) - Remove duplicate code from chat and log-feedback routes
