Description: setup_npm_auth writes the npm auth token into ~/.npmrc but does not enforce restrictive
file permissions (unlike setup_gem_credentials/setup_pypirc), which can leave the token
readable by other users on the machine depending on existing file permissions/umask.

Status:
Insecure .npmrc perms: setup_npm_auth writes the npm auth token to ~/.npmrc but does not enforce restrictive file
permissions (unlike the RubyGems and PyPI credential files), risking unintended secret
exposure via permissive default umask or existing file permissions.

Status:
No audit logging: The new publishing setup functions write sensitive credential files (e.g., /.npmrc,
/.gem/credentials, ~/.pypirc) without any audit logging of the action/outcome, which may
hinder reconstruction of credential-related publishing events depending on policy.

Objective: Ensure comprehensive error handling that provides meaningful context and graceful
degradation

Status:
Unhandled IO errors: The new setup functions perform multiple file reads/writes (e.g., File.read, File.write,
File.open, File.chmod) without handling common IO/permission failures, which could cause
non-actionable task crashes in restricted CI environments.

Set the file permissions of .npmrc to 0o600 after writing to it to protect the
contained credentials.

Improve the check for an existing .pypirc configuration to also verify the
presence of username and password fields before skipping, preventing duplicate
entries.

Replace f.puts with f.write when appending to .pypirc to avoid adding extra
newlines from the heredoc and ensure correct file formatting.

Strip and validate env var values (e.g., reject whitespace-only and
newline-containing tokens) before interpolating into config files to avoid
malformed configs or token-injection via newlines.
