Install n8n past its unsatisfiable canvas dependencies

n8n-nodes-base 2.46.0 moved @napi-rs/canvas-linux-arm64-musl and
-linux-x64-musl from optional into hard dependencies. npm enforces
os/cpu/libc on those, and no combination satisfies both arm64 and x64,
so every install fails with EBADPLATFORM. n8n 2.46.4 reached the latest
tag on 2026-11-03 and the failures started four minutes later.

--force skips the platform check. The matching gnu binary is still
installed through @napi-rs/canvas's own optional dependencies, so canvas
keeps working.
