* fix: override isolated-vm with empty stub to fix CI build

isolated-vm 6.0.2 (transitive dep from n8n-nodes-base) fails to compile
natively on CI (Node 20 + Linux) due to V8 API changes. This package is
not used at runtime by n8n-mcp - we only read node metadata, not execute
nodes. Override with empty-npm-package to avoid the native compilation.

* fix: skip native compilation in fresh install CI check

The fresh install test simulates `npm install n8n-mcp` from scratch,
so package.json overrides don't apply. Use --ignore-scripts to skip
isolated-vm native compilation since n8n-mcp only reads node metadata
and doesn't execute n8n nodes at runtime.
