feat: implement HireFlow MVP features
- AI-powered CV parsing (regex extraction of skills, experience, education) - Multi-channel job posting (LinkedIn, Indeed, Arbetsförmedlingen, Glassdoor, company site) - Collaborative hiring scorecards with 5-criteria scoring system - Dashboard with live stats (candidates, jobs, applications, scorecards) - PostgreSQL schema for candidates, jobs, applications, scorecards - REST API for all CRUD operations - React UI with shadcn/ui components throughout Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
