chore(ipuaro): release v0.29.0

Add High Impact Files section to initial context showing which files
are most critical based on percentage of codebase that depends on them.

Changes:
- Add impactScore field to FileMeta (0-100)
- Add calculateImpactScore() helper function
- Update MetaAnalyzer to compute impact scores
- Add formatHighImpactFiles() to prompts.ts
- Add includeHighImpactFiles config option (default: true)
- 28 new tests (1826 total)

+## [0.29.0] - 2025-12-05 - Impact Score
+
+### Added
+
+- **High Impact Files in Initial Context (v0.29.0)**
+  - New `## High Impact Files` section in initial context
+  - Shows files with highest impact scores (percentage of codebase depending on them)
+  - Table format with File, Impact %, and Dependents count
+  - Files sorted by impact score descending
+  - Default: shows top 10 files with impact score >= 5%
+
+- **Impact Score Computation**
+  - New `impactScore: number` field in `FileMeta` (0-100)
+  - Formula: `(dependents.length / (totalFiles - 1)) * 100`
+  - Computed in `MetaAnalyzer.analyzeAll()` after all files analyzed
+  - New `calculateImpactScore()` helper function in FileMeta.ts
+
+- **Configuration Option**
+  - `includeHighImpactFiles: boolean` in ContextConfigSchema (default: `true`)
+  - `includeHighImpactFiles` option in `BuildContextOptions`
+  - Users can disable to save tokens: `context.includeHighImpactFiles: false`
+
+- **New Helper Function in prompts.ts**
+  - `formatHighImpactFiles()` - formats high impact files table for display
+
+### New Context Format
+
+```
+## High Impact Files
+
+| File | Impact | Dependents |
+|------|--------|------------|
+| utils/validation | 67% | 12 files |
+| types/user | 45% | 8 files |
+| services/user | 34% | 6 files |
+```

+## [0.28.0] - 2025-12-05 - Circular Dependencies in Context
+
+### Added
+
+- **Circular Dependencies in Initial Context (v0.28.0)**
+  - New `## ⚠️ Circular Dependencies` section in initial context
+  - Shows cycle chains immediately without requiring tool calls
+  - Format: `- services/user → services/auth → services/user`
+  - Uses same path shortening as dependency graph (removes `src/`, extensions, `/index`)
+
+- **Configuration Option**
+  - `includeCircularDeps: boolean` in ContextConfigSchema (default: `true`)
+  - `includeCircularDeps` option in `BuildContextOptions`
+  - `circularDeps: string[][]` parameter to pass pre-computed cycles
+  - Users can disable to save tokens: `context.includeCircularDeps: false`
+
+- **New Helper Function in prompts.ts**
+  - `formatCircularDeps()` - formats circular dependency cycles for display
