Summary

Add a fork bootstrap kit, an active upstream auto-sync workflow, a standalone apps/marketing overlay that presents Sim pricing in euros, repo-scoped Cursor Cloud environment setup for Bun + Docker/Compose + local pgvector development, and a Cursor-compatible local Devcontainer image based on the official Microsoft Ubuntu Dev Containers base image. Devcontainer attach now starts only app + db, runs the app container as the bun user with HOME=/home/bun, pre-creates Cursor/Bun temp directories required by Cursor Server install, bakes helper commands into the image via a normal install script, and uses a no-op postCreateCommand; heavier dependency/migration setup is deferred to sim-setup after Cursor has opened.

Fixes #(issue)

Type of Change

• Bug fix
• New feature
• Breaking change
• Documentation
• Other: fork/bootstrap, Cloud environment, and Devcontainer tooling

Testing

• Ran bash fork-kit/bootstrap-fork.sh to generate local ignored env files and .github/workflows/auto-sync.yml.
• Ran bun install.
• Started Postgres 17 + pgvector from docker-compose.local.yml after enabling Docker in this environment.
• Ran bun run db:migrate in packages/db.
• Started bun run dev; verified Sim, Docs, Marketing, and Realtime reached ready/healthy logs.
• Created and executed a local "Hello World" workflow through the running API; response included output.message = "Hello World".
• Verified http://localhost:3003 renders the euro marketing page content.
• Ran bunx turbo run lint:check type-check build --filter=marketing.
• Ran bun run check:api-validation.
• Validated .cursor/environment.json and .devcontainer/devcontainer.json parse as JSON.
• Ran bash -n scripts/cursor-cloud-install.sh, bash -n scripts/cursor-cloud-start.sh, bash -n .devcontainer/post-create.sh, bash -n .devcontainer/sim-commands.sh, and bash -n .devcontainer/install-commands.sh.
• Ran bash scripts/cursor-cloud-install.sh && bash scripts/cursor-cloud-start.sh; verified bun --version is 1.3.13 and docker-compose.local.yml db service remains healthy.
• Ran sudo docker compose -f .devcontainer/docker-compose.yml config.
• Built the updated Devcontainer image with sudo docker build --network=host -f .devcontainer/Dockerfile -t sim-devcontainer-cursor-test ..
• Verified Cursor Server tempdir and baked Devcontainer commands with sudo docker run --rm --user bun -e HOME=/home/bun sim-devcontainer-cursor-test bash -lc 'echo TMPDIR=$TMPDIR && ls -ld "$TMPDIR" ~/.cursor-server && mktemp "$TMPDIR/tmp.XXXXXXXXXX" && which sim-setup sim-start && bun --version'.
• Verified sim-setup wrapper syntax inside the image with sudo docker run --rm --user bun -e HOME=/home/bun sim-devcontainer-cursor-test bash -lc 'bash -n /usr/local/bin/sim-setup && echo wrapper-ok'.
• Built the Cursor Cloud image with sudo docker build --network=host -f .cursor/Dockerfile -t sim-cursor-cloud-env-test ..
