docs: Reflect changes to changelog und push version

- Introduced a `mode` parameter to the `test_RegisterInstanceDecorator` function allowing 'instance' or 'standalone' modes.
- Updated test cases to utilize the new `mode` parameter when registering an instance.
- Disabled specific ESLint rule in `Decorators.test.ts` for deprecation warnings.
- Added an additional test call to `test_RegisterInstanceDecorator` with 'instance' mode.

-
-## [1.2.0]
-
-### Added
-
--   docs: added complete Typedoc-style documentation for all `inject()` overloads  
-    Includes parameter descriptions, usage examples, and detailed error annotations for each variant.
-
-## [1.1.0]
-
-### Added
-
--   feat: exported `inject()` function from the public API via `index.ts`  
-    The function is now available as part of the main module exports.
-
-## [1.0.0]
-
-### Added
-
--   feat: Enable native ESM support using `"type": "module"` and `moduleResolution: "NodeNext"` in the compiler settings.
--   feat: All internal imports now explicitly include `.js` extensions for full Node.js ESM compatibility.
--   feat: Updated `tsconfig.json` to reflect changes for ESM builds (`module: "NodeNext"`, `target: "ES2020"`, etc.).
--   feat(cli): add `--without-extension` (`-x`) flag to optionally omit file extensions in generated import paths
--   feat: introduce `inject()` function as a programmatic alternative to the `@Inject` decorator  
-    Supports optional initializers and constructor instantiation for resolved dependencies.  
-    Designed for cases where decorators are not suitable or dynamic resolution is needed.
--   test: added comprehensive test suite for `inject()` function, covering resolution, initialization, error cases and instantiation behavior
-
-### Changed
-
--   All source files using relative or internal imports were updated to use `.js` extensions to support Node.js ESM runtime resolution.
--   test: update Jest config for ts-jest ESM compatibility and .js import support
--   renamed internal parameter `necessary` → `isNecessary` for naming clarity
-
-### Removed
-
--   Removed implicit support for CommonJS-style imports without file extensions.
 
 ### Deprecated
 
--   Support for CommonJS consumers using `require()` is no longer available. Use `import` with an ESM-compatible environment instead.
-
-### Fixed
-
-### Security
-
-### ⚠️ Breaking Changes
-
--   **BREAKING CHANGE**: This version migrates the entire codebase to native ES modules.
-    -   Consumers must use Node.js in ESM mode or compatible bundlers.
-    -   Import paths now include `.js` extensions.
-    -   Using `require()` (CommonJS) to load this library will no longer work.
-    -   All consuming projects must either:
-        -   Use `"type": "module"` in their `package.json`, or
-        -   Use an ESM-aware bundler (e.g. Webpack, Vite, etc.)

--   refactor: consolidate registration decorators
-    Introduced Register decorator to handle class and instance registration in the DI container.

-    Added support for marking dependencies as deprecated with a warning logged upon first resolution.
-    Updated documentation with examples and notes on deprecation.

 ## [0.2.0]
 
 ### Added
 
--   Add pre release building to release workflow on dev/\* branches an version changes.
--   feat: Introduced a new CLI command `tsinjex-generate` to automate the generation of import statements for registered dependencies.  
-    The command scans `.ts` files for `@Register` and `@RegisterInstance` decorators and generates an `auto-imports.ts` file.  
-    This ensures that all registered dependencies are automatically included without requiring manual imports.  
-    The CLI can be executed via `npx tsinjex-generate` or added as a script in `package.json` for easier integration.
