feat(context): implement R005 decision scope cascade and derive scope from slice metadata
Fix 1 - Fallback cascade:
- inlineDecisionsFromDb() now cascades: milestone+scope → milestone only → null
- When scoped query returns empty AND scope was provided, retries without scope
- Falls back to milestone-level decisions when no scope-specific ones exist
Fix 2 - Derive scope from slice metadata:
- Added deriveSliceScope(title, description?) helper function
- Extracts first meaningful noun (filters stopwords and generic words)
- Examples: 'Auth Middleware & Protected Route' → 'auth'
'Integration Testing' → undefined (too generic)
- Wired into buildPlanSlicePrompt and buildResearchSlicePrompt
Added comprehensive test suite (13 tests) covering:
- Keyword extraction from slice titles
- Generic title detection
- Cascade fallback behavior
- Integration between scope derivation and cascade
