feat: add @automaker/dependency-resolver package

ELIMINATES CODE DUPLICATION: This file was duplicated in both server and UI (222 lines each).

- Extract feature dependency resolution using topological sort
- Implement Kahn's algorithm with priority-aware ordering
- Detect circular dependencies using DFS
- Check for missing and blocking dependencies
- Provide helper functions (areDependenciesSatisfied, getBlockingDependencies)

This package will replace:
- apps/server/src/lib/dependency-resolver.ts (to be deleted)
- apps/ui/src/lib/dependency-resolver.ts (to be deleted)

Impact: Eliminates 222 lines of duplicated code.

Dependencies: @automaker/types
