⚠️ Potential issue | 🟡 Minor | ⚡ Quick win

Verify no_proxy normalization for consistency.

The test sets both NO_PROXY and no_proxy with malformed input but only verifies NO_PROXY is normalized. For consistency with other tests in this file (lines 58-67, 80-89), also verify no_proxy is normalized correctly.

✅ Add assertions for no_proxy 
    expect(env.NO_PROXY).not.toContain(",,");
    expect(env.NO_PROXY).not.toMatch(/^,|,$/);
    expect(env.NO_PROXY).toContain("corp.internal");
    expect(env.NO_PROXY).toContain("other.com");
    expect(env.NO_PROXY).toContain("localhost");
+   expect(env.no_proxy).not.toContain(",,");
+   expect(env.no_proxy).not.toMatch(/^,|,$/);
+   expect(env.no_proxy).toContain("corp.internal");
+   expect(env.no_proxy).toContain("other.com");
+   expect(env.no_proxy).toContain("localhost");
  });

In `@src/lib/subprocess-env.test.ts` around lines 44 - 56, The test only asserts
normalization for env.NO_PROXY; update the same test ("strips empty segments
from a NO_PROXY with doubled or trailing commas") to also assert env.no_proxy is
normalized the same way—after calling withLocalNoProxy(env) add checks that
env.no_proxy does not contain ",,", does not start or end with a comma
(/^,|,$/), and contains "corp.internal", "other.com", and "localhost", mirroring
the existing expectations for env.NO_PROXY and using the same symbols
(withLocalNoProxy, env.NO_PROXY, env.no_proxy).
