chore(node-client-sdk): adding additional option values

[joker23]

This PR will add some missed option values:

• NodeIdentifyOptions extends LDIdentifyOptions with an optional hash field; per-identify hash overrides the config-level hash for that call and all subsequent requests until the next identify
• NodeInfo accepts wrapperName/wrapperVersion and forwards them to sdkData(); NodePlatform reads these from ValidatedOptions
• Also adding unit tests for datamanager

---

Note

Medium Risk
Secure Mode hash changes which contexts are accepted on stream/poll URLs; behavior is covered by tests but mistakes could block flag delivery for signed contexts.

Overview
Adds Secure Mode support on identify and wires wrapper SDK metadata through the Node client-side SDK.

Per-identify hash: New NodeIdentifyOptions (exported as LDIdentifyOptions) adds an optional Secure Mode hash. NodeDataManager keeps a _currentHash from config or the latest identify (per-identify wins; empty string is ignored), sets the h query parameter on stream/poll connections, and uses it in makeRequestor. A later identify without hash falls back to the config hash or omits h. Public identify typings now use NodeIdentifyOptions.

Wrapper metadata: wrapperName and wrapperVersion are validated in node options, passed from NodePlatform into NodeInfo, and included in sdkData() when set. Option validation now iterates NodeOptions keys so base options with validators are handled consistently.

Tests: New NodeDataManager tests cover hash behavior across streaming, polling, mode switches, bootstrap, and fallback; platform/options tests cover wrapper fields.
