chore(ipuaro): release v0.26.0

Extract decorators from classes and methods for NestJS/Angular support.
Decorators are now shown in initial context:
- @Controller('users') class UserController
- @Get(':id') async getUser(id: string): Promise<User>

Changes:
- Add decorators field to FunctionInfo, MethodInfo, ClassInfo
- Update ASTParser to extract decorators from tree-sitter nodes
- Update formatFileSummary to display decorators prefix
- Add 18 unit tests for decorator extraction and formatting

+## [0.26.0] - 2025-12-05 - Rich Initial Context: Decorator Extraction
+
+### Added
+
+- **Decorator Extraction (0.24.4)**
+  - Functions now show their decorators in initial context
+  - Classes now show their decorators in initial context
+  - Methods show decorators per-method
+  - New format: `@Controller('users') class UserController`
+  - Function format: `@Get(':id') async getUser(id: string): Promise<User>`
+  - Supports NestJS decorators: `@Controller`, `@Get`, `@Post`, `@Injectable`, `@UseGuards`, etc.
+  - Supports Angular decorators: `@Component`, `@Injectable`, `@Input`, `@Output`, etc.
+
+- **FileAST.ts Enhancements**
+  - `decorators?: string[]` field on `FunctionInfo`
+  - `decorators?: string[]` field on `MethodInfo`
+  - `decorators?: string[]` field on `ClassInfo`
+
+- **ASTParser.ts Enhancements**
+  - `formatDecorator()` - formats decorator node to string (e.g., `@Get(':id')`)
+  - `extractNodeDecorators()` - extracts decorators that are direct children of a node
+  - `extractDecoratorsFromSiblings()` - extracts decorators before the declaration in export statements
+  - Decorators are extracted for classes, methods, and exported functions
+
+- **prompts.ts Enhancements**
+  - `formatDecoratorsPrefix()` - formats decorators as a prefix string for display
+  - Used in `formatFunctionSignature()` for function decorators
+  - Used in `formatFileSummary()` for class decorators
+
+### New Context Format
+
+```
+### src/controllers/user.controller.ts
+- @Controller('users') class UserController extends BaseController
+- @Get(':id') @Auth() async getUser(id: string): Promise<User>
+- @Post() @ValidateBody() async createUser(data: UserDTO): Promise<User>

+## [0.25.0] - 2025-12-04 - Rich Initial Context: Interface Fields & Type Definitions
+
+### Added
+
+- **Interface Field Definitions (0.24.2)**
+  - Interfaces now show their fields in initial context
+  - New format: `interface User { id: string, name: string, email: string }`
+  - Readonly fields marked: `interface Config { readonly version: string }`
+  - Extends still supported: `interface AdminUser extends User { role: string }`
+
+- **Type Alias Definitions (0.24.2)**
+  - Type aliases now show their definitions in initial context

+  - Union types: `type Status = "pending" | "active" | "done"`
+  - Intersection types: `type AdminUser = User & Admin`
+  - Function types: `type Handler = (event: Event) => void`
+  - Long definitions truncated at 80 characters with `...`
+
+- **New Helper Functions in prompts.ts**
+  - `formatInterfaceSignature()` - formats interface with fields

+  - `truncateDefinition()` - truncates long type definitions
+
+### Changed
+
+- **FileAST.ts**
+  - Added `definition?: string` field to `TypeAliasInfo` interface
+
+- **ASTParser.ts**

+  - Supports all type kinds: simple, union, intersection, object, function, generic, array, tuple
+
+- **prompts.ts**
+  - `formatFileSummary()` now uses `formatInterfaceSignature()` for interfaces
+  - `formatFileSummary()` now uses `formatTypeAliasSignature()` for type aliases
+
+### New Context Format
+
+```
+### src/types/user.ts
+- interface User { id: string, name: string, email: string }
+- interface UserDTO { name: string, email?: string }
+- type UserId = string
+- type Status = "pending" | "active" | "done"
+- type AdminUser = User & Admin
+```
