feat: Initialize monorepo structure and comprehensive documentation

This commit establishes the new monorepo architecture for the KROW Workforce platform.

Key changes include:
- Reorganized project into `frontend-web`, `mobile-apps`, `firebase`, `scripts`, and `secrets` directories.
- Updated `Makefile` to support the new monorepo layout and automate Base44 export integration.
- Fixed `scripts/prepare-export.js` for ES module compatibility and global component import resolution.
- Created and updated `CONTRIBUTING.md` for developer onboarding.
- Restructured, renamed, and translated all `docs/` files for clarity and consistency.
- Implemented an interactive internal launchpad with diagram viewing capabilities.
- Configured base Firebase project files (`firebase.json`, security rules).
- Updated `README.md` to reflect the new project structure and documentation overview.

+# KROW Project Plan & Task Breakdown
+
+This document breaks down the technical roadmap into actionable tasks, assigned by role, ready to be converted into GitHub Issues.
+
+---
+
+## Milestone 1: Foundation & Dev Environment Setup
+
+*Goal: Establish a fully functional, shared `dev` environment on GCP/Firebase that all developers can connect to.*
+
+### Infrastructure & Tooling (Primarily CTO)
+- **Issue:** `[Infra] Setup Enpass for Team Credential Management`
+  - **Description:** Configure the team's Enpass vault and establish the process for sharing secrets and service account keys.
+- **Issue:** `[Infra] Create GCP/Firebase Projects (dev, staging, prod)`
+  - **Description:** Set up the three distinct Google Cloud projects and associated Firebase projects. Enable required APIs (Auth, Cloud SQL, Data Connect).
+- **Issue:** `[Infra] Create Multi-Env Makefile`
+  - **Description:** Create the main `Makefile` inspired by the reference project. It should handle environment switching (`ENV=dev/staging`) and orchestrate all build/deploy tasks.
+- **Issue:** `[Infra] Setup Shared Dev Database`
+  - **Description:** Provision the initial Cloud SQL for PostgreSQL instance for the `dev` environment.
+
+### Backend & Web (Dev 1)
+- **Issue:** `[Backend] Define GraphQL Schema for Core Entities`
+  - **Description:** Translate `Event`, `Staff`, `Vendor`, and `User` schemas from `api_specification.md` into `.gql` files for Data Connect.
+- **Issue:** `[Backend] Deploy Initial Schema & Operations to Dev Env`
+  - **Description:** Use the `Makefile` to deploy the initial Data Connect schema and basic `list/get` queries to the `dev` project.
+- **Issue:** `[Web] Generate TypeScript SDK for Dev Env`
+  - **Description:** Configure and run the SDK generation command to create the TypeScript SDK pointing to the `dev` environment.
+- **Issue:** `[Web] Connect Web App to Dev Backend`
+  - **Description:** Modify the web app to use the generated SDK. The goal is to authenticate and display a list of events from the shared `dev` backend.
+
+### Mobile (Dev 2)
+- **Issue:** `[Mobile] Generate Flutter SDK for Dev Env`
+  - **Description:** Configure and run the SDK generation command to create the Flutter SDK pointing to the `dev` environment.
+- **Issue:** `[Mobile] Implement Firebase Auth Flow`
+  - **Description:** Ensure both mobile apps can sign in and sign up using Firebase Auth against the `dev` project.
+- **Issue:** `[Mobile] Create Proof-of-Concept Screen`
+  - **Description:** Build a simple screen in the Staff app that authenticates and fetches a list of events from the `dev` backend using the new SDK.
+
+---
+
+## Milestone 2: Core Feature Implementation
+
+*Goal: Achieve functional parity with the Base44 prototype across all platforms, using the shared `dev` backend.*
+
+### Backend (Dev 1)
+- **Epic:** `[Backend] Implement Full API Logic`
+  - **Description:** Create all necessary GraphQL queries and mutations in Data Connect for all entities defined in `api_specification.md`. Deploy them continuously to the `dev` environment.
+
+### Web (Dev 1, with support from Dev 2)
+- **Epic:** `[Web] Full Application Re-wiring`
+  - **Description:** Systematically replace all data-fetching logic in the web app to use the TanStack Query hooks from the generated Data Connect SDK.
+
+### Mobile (Dev 2)
+- **Epic:** `[Mobile] Full Application Re-wiring`
+  - **Description:** Refactor the `repositories` and `api_providers` in both the Client and Staff Flutter apps to use the generated Data Connect SDK for all network calls.
+
+---
+
+## Milestone 3: Production Readiness & Go-Live
+
+*Goal: Automate, secure, and deploy the entire platform to production.*
+
+### Infrastructure & DevOps (CTO & Team)
+- **Issue:** `[CI/CD] Configure Web App Deployment Pipeline`
+  - **Description:** Set up a GitHub Actions pipeline that builds and deploys the web app to Firebase Hosting, with separate jobs for `staging` and `prod`.
+- **Issue:** `[CI/CD] Configure Mobile App Deployment with CodeMagic`
+  - **Description:** Set up CodeMagic pipelines to build and deploy the iOS and Android apps to TestFlight/Play Store Internal Testing.
+- **Issue:** `[CI/CD] Configure Backend Deployment Pipeline`
+  - **Description:** Automate the deployment of the Data Connect schema and operations (`firebase deploy --only dataconnect`).
+- **Issue:** `[Data] Create & Test Initial Data Import Scripts`
+  - **Description:** Write scripts to populate the production database with any necessary initial data.
+- **Issue:** `[QA] Deploy to Staging & Perform E2E Testing`
+  - **Description:** Use the `Makefile` (`make deploy ENV=staging`) to deploy the entire stack to the staging environment for full end-to-end testing.
+- **Issue:** `[Ops] Final Production Deployment`
+  - **Description:** Run the production deployment (`make deploy ENV=prod`) and execute data import scripts.
+- **Issue:** `[Ops] Setup Monitoring & Alerting`
+  - **Description:** Configure monitoring dashboards in Google Cloud for the database, API, and application performance.
