feat(#137): create Forced Continuation Prompt System

Implement prompt generation system that produces continuation prompts
based on verification failures to force AI agents to complete work.

Service:
- generatePrompt: Complete prompt from failure context
- generateTestFailurePrompt: Test-specific guidance
- generateBuildErrorPrompt: Build error resolution
- generateCoveragePrompt: Coverage improvement strategy
- generateIncompleteWorkPrompt: Completion requirements

Templates:
- base.template: System/user prompt structure
- test-failure.template: Test fix guidance
- build-error.template: Compilation error guidance
- coverage.template: Coverage improvement strategy
- incomplete-work.template: Completion requirements

Constraint escalation:
- Attempt 1: Normal guidance
- Attempt 2: Focus only on failures
- Attempt 3: Minimal changes only
- Final: Last attempt warning

Priority levels: critical/high/normal based on failure severity

Tests: 24 passing with 95.31% coverage

Fixes #137
