Switch Docker build to pnpm to avoid Bun registry 404s

[Copilot]

Docker builds failed on bun install --frozen-lockfile with 404s for some npm packages during image creation.

• Build toolchain: Replace Bun-based install stages with pnpm on Node 20, pin npm registry, and enable corepack for pnpm. Runtime now executes node server.js.
• Dependencies: Add pnpm-lock.yaml, include framer-motion and @types/pg to satisfy TypeScript checks. Update .dockerignore to skip pnpm store artifacts.

Example (install stage):

FROM node:20-slim AS install
WORKDIR /temp/dev
COPY package.json pnpm-lock.yaml ./
RUN corepack enable && corepack prepare pnpm@9.15.4 --activate
RUN pnpm install --frozen-lockfile

Original prompt

I am building a Docker image for a Next.js project using Bun, but the build fails at bun install --frozen-lockfile due to 404 errors fetching some npm packages.
Please search for solutions to this error, including alternative Bun install flags or registry settings.
Use internet search to find fixes for Bun 404 errors during Docker builds.
If no Bun solution works, update the Dockerfile to use pnpm instead of Bun for installing dependencies.
Make sure the .dockerignore and Dockerfile are updated accordingly.

Addressed by switching Docker install to pnpm with registry pinning and updated runtime (commit 9a452c3). Let me know if you’d like any adjustments or a Bun-based workaround retained instead.
