Document requestOptions for SSL/TLS configuration; fix broken rpOptions example

[Copilot]

config.requestOptions already forwards agentOptions to postman-request on every call, but this was entirely undocumented — leaving Node 18+ users stuck on EPROTO ... unsafe legacy renegotiation disabled errors with no clear path forward. The README also had a broken SOCKS proxy example referencing a non-existent rpOptions config key.

Changes

• README.md: Fix rpOptions → requestOptions in SOCKS proxy example; add SSL/TLS configuration section
• example/pass_request_options.js: Show both init-time (config.requestOptions) and per-call usage
• test/unit.js: Add tests verifying config.requestOptions forwarding across all HTTP methods, generated functions, and per-call override

Usage

const vault = require('node-vault')({
  endpoint: 'https://vault.example.com:8200',
  token: 'MY_TOKEN',
  requestOptions: {
    agentOptions: {
      securityOptions: 'SSL_OP_LEGACY_SERVER_CONNECT',
    },
  },
});

Per-call overrides work too:

vault.read('secret/hello', {
  agentOptions: { securityOptions: 'SSL_OP_LEGACY_SERVER_CONNECT' },
});

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:

• https://api.github.com/graphql
  • Triggering command: /usr/bin/gh gh pr ready 279 (http block)
  • Triggering command: /usr/bin/gh gh auth status (http block)
  • Triggering command: /usr/bin/gh gh api graphql -f query=mutation { markPullRequestReadyForReview(input: { pullRequestId: "" }) { pullRequest { isDraft } } } (http block)
• https://api.github.com/repos/nodevault/node-vault/pulls/279
  • Triggering command: /usr/bin/gh gh api repos/nodevault/node-vault/pulls/279 --jq .node_id (http block)
  • Triggering command: /usr/bin/curl curl -s -H Authorization: ****** -H Accept: application/vnd.github+json REDACTED (http block)
  • Triggering command: /usr/bin/curl curl -v -H Authorization: ****** -H Accept: application/vnd.github+json REDACTED (http 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)
