- fix(restart-all.sh): use taskkill to reliably kill anvil.exe on Windows - fix(restart-all.sh): replace --root flag with cd-based approach (--root incompatible with Unix paths on Windows forge.exe) - fix(restart-all.sh): clear broadcast/cache dirs before each deploy to avoid stale state conflicts - fix(restart-all.sh): show forge output on failure for easier debugging - chore: add package-lock.json and next-env.d.ts for all 4 Next.js apps (generated by npm install) - chore: tsconfig.json reformatted by Next.js (expanded arrays) Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
- add .gitattributes: force LF line endings for all .sh, .sol, .ts, .json, .md files (prevents CRLF issues when running .sh scripts from WSL) - docs: add section §11 P03 E-Commerce with Windows-specific lessons: forge --root incompatible with Unix paths, pkill vs taskkill, broadcast cache conflicts, set -e swallowing forge errors, cast send for testing without Stripe Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
- trap cleanup on EXIT/INT/TERM: kills all child PIDs, node.exe, anvil.exe
- track CHILD_PIDS for Anvil and all 4 Next.js apps
- preserve existing Stripe keys from .env.local instead of overwriting
with bash ${VAR:-placeholder} syntax that Next.js doesn't expand
