* Update TypeScript configuration across multiple packages to correct plugin path key from "path" to "paths" and add reference to process-worker typings in index.electron.ts.

* Remove reference to process-worker typings in index.electron.ts and add new process-worker typings file for global Process augmentation.

* Refactor TypeScript build configurations across multiple packages by removing tsconfig.dist.json files and updating build scripts to use default TypeScript compilation. Adjusted compiler options to target ES2021 and enable declaration generation.

* Update TypeScript configuration in api package to refine include and exclude patterns for better file management.

* Update build script in api package to ensure migration SQL files are copied to the correct directory by creating the destination folder if it doesn't exist.

* Update TypeScript configurations in crdt and desktop-electron packages to refine include and exclude patterns for improved file management.

* Update TypeScript dependencies across multiple packages to include typescript-strict-plugin for enhanced type checking and maintain consistency in package.json files.
