📋 Summary of Changes

This PR refactors the DevImpact codebase into a Feature-Driven Scalable Next.js Architecture (src/) to improve modularity, isolation, developer velocity, and maintainability as the project grows.

🏗️ Architectural Changes:

  1. Feature Domain Modules (src/features/):

    • comparison/: Side-by-side developer comparison components, service orchestration, tests, and types.
    • developer/: Single developer profile components, PR metrics, repository cards, tests, and types.
    • leaderboard/: Country ranking table, country discovery grid, caching queries, and types.
    • scoring/: Core scoring engine (Repo, PR, Contribution, Language scores, logarithmic formulas), unit tests, and methodology visualizer.
    • Each feature encapsulates its own components/, services/, tests/, types.ts, and public API barrel export (index.ts).
  2. Shared Infrastructure (src/lib/):

    • Decoupled adapters into dedicated modules: cache/, db/, geo/, github/, i18n/, logger/, and seo/.
  3. Domain-Agnostic UI & Layout (src/components/):

    • Modularized into ui/ primitives, layout/ chrome (Navbar, Footer, MobileNav), providers/ (Theme, Locale), and seo/.
  4. Thin App Router (src/app/):

    • Clean Next.js route handlers and pages delegating business logic to feature services.
  5. Path Aliases & Tooling:

    • Configured @/features/*, @/lib/*, @/components/*, @/types/*, @/data/*, @/utils/*, and @/locales/* across tsconfig.json, tailwind.config.ts, and vitest.config.ts.
    • Updated standalone scripts (scripts/calculate-next-country.ts, scripts/init-db.ts, scripts/validate-locales.js).
  6. Documentation Overhaul:

    • ARCHITECTURE.md: Created a comprehensive guide with architectural philosophy, sequence diagrams, directory maps, import rules, and step-by-step contributor cookbooks.
    • CONTRIBUTING.md & README.md: Aligned project trees, tech stack references, and testing instructions.
    • ops/README.md & algorithm.md: Cleaned up path references and linked to production implementations.

🧪 Quality Assurance & Validation

  • Unit & Integration Tests: 14 test suites, 113/113 tests passed (pnpm test).
  • Type Checking: 0 TypeScript errors (npx tsc --noEmit).
  • Localization Sync: 100% key parity between English and Arabic (pnpm validate-locales).
  • Production Build: Verified full build compiles successfully (pnpm build).
  • Code Style & Linting: Formatted with Prettier and validated with ESLint.

Additionally, at the time of submission of this PR:

  • The referred issue is not blocked currently
  • All unittests passed after changes were made

…umentation

- Reorganized codebase under `src/` following a Feature-Driven Scalable Next.js Architecture:
  - `src/features/` (domain modules: comparison, developer, leaderboard, scoring with colocated components, services, tests, types, and barrel exports)
  - `src/lib/` (infrastructure adapters: cache, db, geo, github, i18n, logger, seo)
  - `src/components/` (shared domain-agnostic UI: ui, layout, providers, seo)
  - `src/app/` (thin routing controllers, layouts, and API routes)
  - `src/locales/`, `src/data/`, `src/types/`, `src/utils/`
- Updated path aliases in `tsconfig.json`, `tailwind.config.ts`, and `vitest.config.ts` (`@/features/*`, `@/lib/*`, `@/components/*`, etc.).
- Updated script paths in `scripts/calculate-next-country.ts`, `scripts/init-db.ts`, and `scripts/validate-locales.js`.
- Created comprehensive `ARCHITECTURE.md` documentation detailing system design, sequence flows, encapsulation rules, and step-by-step contributor cookbooks.
- Updated `README.md`, `CONTRIBUTING.md`, and `algorithm.md` to align with the new architecture.
- Replaced hardcoded machine/absolute paths in markdown files with relative paths.
