Implement Skills feature: filesystem-based skills with agent assignment

- Add SkillService: scans data/skills/ directory, parses _meta.json and SKILL.md frontmatter - Add SkillEndpoint: REST API for listing skills and managing agent-skill assignments - Add agent_skills DB table for agent-to-skill mapping (only relation in DB, skills live on filesystem) - Extend SystemPromptBuilder: inject assigned skills' SKILL.md content into system prompt - Extend ChatEndpoint + SessionEndpoint: load agent skills and pass to prompt builder - Frontend: skill checkboxes in agent form, API functions for skill management - Add form.css styling for skill list items
