Fix installation failure for packages with empty bin field

[Copilot]

Packages with "bin": "" or "bin": {"cmd": ""} in package.json fail installation with "Failed to ensure binary is executable". The parser creates bin entries for empty paths, which later resolve to the package directory itself when joined, causing the executable check to fail on a directory.

Changes

• String bin values: Return empty vector when path is empty
• Object bin values: Use filter_map to skip entries with empty path values
• Tests: Added coverage for both empty string and mixed empty/valid object cases

// Before: Created bin entry for empty string
vec![(name.clone(), "")]  // Resolves to package directory

// After: Skip empty paths entirely
if bin_path.is_empty() {
    Vec::new()
} else {
    vec![(name.clone(), bin_path)]
}

This matches cnpm behavior and allows legacy packages with empty bin fields to install successfully.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• github.com (HTTP Only)
  • Triggering command: /usr/bin/ssh /usr/bin/ssh -o SendEnv=GIT_PROTOCOL [email protected] git-upload-pack 'utooland/next.js.git' (packet block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
