feat: httpStream

[RohitKushvaha01]

Closes #2827

[greptile-apps]

Greptile Summary

The PR adds a Cordova-backed streaming HTTP API that exposes native response data through a WHATWG ReadableStream.

• Adds Android request streaming, cancellation, pause/resume backpressure, timeout handling, redirects, headers, and request bodies.
• Aligns the JavaScript API, TypeScript declarations, Cordova manifest, and native service actions.
• Adds unit coverage for incremental delivery, metadata, errors, cancellation, concurrent requests, and backpressure.

Confidence Score: 5/5

The PR appears safe to merge because no blocking failure remains.
