Replace broad `.env*` ignore rule with explicit entries for real env files (`.env`, `.env.local`, `.env.development`, `.env.test`, `.env.production`) while preserving `.env.example` and adding exceptions for the new `.env.development.example`, `.env.test.example`, and `.env.production.example` templates.
Add environment-specific example files to document required variables for development, test, and production setups, including API base URLs, WebSocket endpoints, API timeouts, Auth.js secret, OAuth credentials (Google, Facebook), and Cloudflare CDN configuration.
Introduce a tracked .env.example file documenting all required environment
variables (app env, API/WebSocket base URLs, timeouts, Google/Facebook OAuth
credentials, Cloudflare CDN zone/token). Update .gitignore to allow this
file despite the blanket .env* ignore rule. Also simplify the push
success/failure output in scripts/deploy/_deploy_lib.sh by removing
verbose troubleshooting hints.
Add allowBuilds configuration for sharp and unrs-resolver packages
to permit their postinstall scripts to run, and ignore the local
.pnpm-store directory.
