fix(ci): exclude npm/ binaries from .node file search in publish workflow

The find command in 'Copy to platform package' was picking up the
already-committed .node files in crates/ruvector-attention-node/npm/
and then trying to cp them to themselves, causing exit code 1.

Fix: add `! -path "*/npm/*"` so only freshly built target artifacts
are found. Applied to both publish-all.yml and build-attention.yml.
