Set up pnpm workspace and synchronize package versions

[ErickDevv]

This pull request introduces a monorepo structure with improved tooling, unified scripts, and shared configuration for linting and testing across the api and web packages. The main changes include adopting Turborepo for task orchestration, adding a shared ESLint config package, synchronizing package versions, and updating CI workflows and scripts for consistency and efficiency.

Monorepo structure and tooling

• Added a root package.json with scripts for building, testing, linting, and development using Turborepo, and set up Husky for Git hooks.
• Introduced a turbo.json configuration to define task dependencies, caching, and outputs for builds, tests, linting, and development.
• Added a pnpm-workspace.yaml to define workspace packages and build settings for the monorepo.

Shared ESLint configuration

• Created a new @opengalley/eslint-config package with base and React-specific configurations, and updated both api and web to use these shared configs. [1] [2] [3] [4] [5]
• Updated api/package.json and web/package.json to add lint scripts and depend on the shared ESLint config. [1] [2] [3] [4] [5]

Version synchronization

• Added a sync-version.sh script and Husky pre-commit hook to automatically sync the root version to all package manifests (api, web, and eslint-config). [1] [2]

CI and testing improvements

• Updated GitHub Actions workflows to use unified lint and test jobs with Turborepo, improving efficiency and consistency for both API and web. [1] [2] [3] [4]
• Simplified the local test.sh script to run tests via Turborepo and updated the E2E test command to use filtering for the web package.

Other improvements

• Updated TypeScript config in api for modern module resolution.

These changes collectively improve code quality, developer experience, and maintainability by standardizing tooling and configuration across the monorepo.- Created pnpm-workspace.yaml to define workspace packages.

• Added sync-version.sh script to synchronize version across packages.
• Updated test.sh to run unit tests and E2E tests using turbo.
• Introduced turbo.json for task management with Turbo.
• Added ESLint configuration for the web package.
• Bumped version of opengalley-web to 0.2.0 and added lint script.
