fix: resolve critical package issues and update imports

CRITICAL FIXES:
- Fix dependency-resolver ES module failure by reverting to CommonJS
  - Removed "type": "module" from package.json
  - Changed tsconfig.json module from "ESNext" to "commonjs"
  - Added exports field for better module resolution
  - Package now works correctly at runtime

- Fix Feature type incompatibility between server and UI
  - Added FeatureImagePath interface to @automaker/types
  - Made imagePaths property accept multiple formats
  - Added index signature for backward compatibility

HIGH PRIORITY FIXES:
- Remove duplicate model-resolver.ts from apps/server/src/lib/
  - Update sdk-options.ts to import from @automaker/model-resolver
  - Use @automaker/types for CLAUDE_MODEL_MAP and DEFAULT_MODELS

- Remove duplicate session types from apps/ui/src/types/
  - Deleted identical session.ts file
  - Use @automaker/types for session type definitions

- Update source file Feature imports
  - Fix create.ts and update.ts to import Feature from @automaker/types
  - Separate Feature type import from FeatureLoader class import

MEDIUM PRIORITY FIXES:
- Remove unused imports
  - Remove unused AbortError from agent-service.ts
  - Remove unused MessageSquare icon from kanban-card.tsx
  - Consolidate duplicate React imports in hotkey-button.tsx

- Update test file imports to use @automaker/* packages
  - Update 12 test files to import from @automaker/utils
  - Update 2 test files to import from @automaker/platform
  - Update 1 test file to import from @automaker/model-resolver
  - Update dependency-resolver.test.ts imports
  - Update providers/types imports to @automaker/types

VERIFICATION:
- Server builds successfully ✓
- All 6 shared packages build correctly ✓
- Test imports updated and verified ✓
