fix: inject linux-musl sharp binaries into build/ to fix 502 on Dokploy

Browse Source 
build.sh runs npm run build on macOS, so only the host's sharp binary
(darwin-arm64) got traced into the standalone output. The container
runs node:20-alpine (Linux, musl libc), which cannot load that binary
- the server crashed at runtime, causing a 502 even though the docker
build itself succeeded.

npm pack can fetch another platform's prebuilt sharp/libvips tarballs
without an install-time OS check, so build.sh now pulls the
linux-musl x64 and arm64 builds directly into build/node_modules and
drops the now-unused host binary.

# `sharp` ships platform-specific native binaries as optional dependencies.
# Since this build runs on the host machine (macOS), only the host's binary
# (e.g. darwin-arm64) gets installed/traced - it will NOT load inside the
# Linux (node:20-alpine, musl libc) container and crashes the server at
# runtime (surfaces as a 502 after an otherwise-successful docker build).
# `npm pack` can fetch another platform's prebuilt tarball without an
# install-time OS/arch check, so pull the linux-musl builds directly and
# drop them into node_modules alongside the host's.
