Verification: .env.example already exists and satisfies all requirements

[Copilot]

Issue reports missing .env.example file for environment variable documentation. Investigation confirms the file already exists and fully addresses all stated requirements.

Current State

The .env.example file exists at repository root with:

• 29 environment variables documented (OpenAI, Google Maps, Stripe, Firebase, Hugging Face)
• Placeholder values for all keys (e.g., sk-proj-XXXX, AIzaSyXXXX)
• Source URLs for obtaining each API key
• Required/Optional labels (4 required sections, 3 optional sections)
• Perfect sync with lib/config/app_config.dart (no orphaned or missing variables)

Verification

# Setup instructions already in README.md
cp .env.example .env
# Edit .env with actual keys

# Variables include (subset):
OPENAI_API_KEY=sk-proj-XXXX           # https://platform.openai.com/api-keys
GOOGLE_MAPS_API_KEY=AIzaSyXXXX        # https://console.cloud.google.com/...
STRIPE_PUBLISHABLE_KEY=pk_test_XXXX   # https://dashboard.stripe.com/apikeys

.gitignore properly excludes .env files. Documentation references setup in README.md and docs/GETTING_STARTED.md.

Resolution

No changes required. Issue resolved by previous commit (e1fb862, 2026-01-08).

<issue_title>Missing .env.example Template for Environment Variables</issue_title>
<issue_description>## ⚠️ High Priority Issue

Problem

There is no .env.example file to guide developers on what environment variables are needed.

Impact

• New developers don't know what API keys are required
• Difficult to set up the project
• No documentation of required configuration

Expected Behavior

A .env.example file should exist with:

• All required environment variables
• Placeholder values
• Comments explaining where to get each key
• Documentation of optional vs required variables

Solution

Create a .env.example file with:

# OpenAI API Key
OPENAI_API_KEY=your_openai_api_key_here

# Google Maps API Key
GOOGLE_MAPS_API_KEY=your_google_maps_api_key_here

# ... etc
