refactor: centralize types and extract seed data (Task 1.1)
- Create types/ directory with canonical domain type definitions
- session.ts, tool-instance.ts, tool-type.ts, git-repository.ts
- config-folder.ts, tool-config.ts, project.ts, user.ts, api-response.ts
- Move inline types from api modules to types/ with backward-compatible re-exports
- Update all consumers (pages, components, state) to import from types/
- Extract seed_builtin_tool_types from main.py to seeds/builtin_tool_types.py
- Ensure Session, ToolInstance, ToolType, GitRepository defined exactly once
Quality gates: tsc (pass), eslint (pass), Python syntax (pass)
