Added

• Employee onboarding flow: records view with checklist detail panel, templates for reusable step sets, progress tracking per employee
• Onboarding records stored in onboarding/ directory as one .md file per employee with YAML frontmatter for steps and metadata
• Onboarding templates stored in onboarding-templates/ directory
• API routes: GET/POST /api/onboarding, GET/PUT/DELETE /api/onboarding/:id, full CRUD for /api/onboarding-templates

Fixed

• Onboarding API PUT route now performs safe partial update: only merges fields explicitly present in the request body, preventing undefined values from wiping existing frontmatter fields (employeeName, role, startDate)
