refactor: extract auto-mode-service into modular services

Reduce auto-mode-service.ts from 1308 to 516 lines (60% reduction) by
extracting reusable functionality into shared packages and services:

- Add feature prompt builders to @automaker/prompts (buildFeaturePrompt,
  buildFollowUpPrompt, buildContinuationPrompt, extractTitleFromDescription)
- Add planning prompts and task parsing to @automaker/prompts
- Add stream processor utilities to @automaker/utils (sleep, processStream)
- Add git commit utilities to @automaker/git-utils (commitAll, hasUncommittedChanges)
- Create ProjectAnalyzer service for project analysis
- Create FeatureVerificationService for verify/commit operations
- Extend FeatureLoader with updateStatus, updatePlanSpec, getPending methods
- Expand FeatureStatus type to include all used statuses
- Add PlanSpec and ParsedTask types to @automaker/types
