Note

Medium Risk
Adds a new client.browsers.curl API surface (new request/response types) that routes HTTP requests through a browser session, so incorrect parameter/response handling could break consumers. Remaining changes are primarily versioning/docs/codegen updates with low behavioral impact.

Overview
Releases v0.50.0 of the SDK, updating version metadata (package.json, src/version.ts, release manifests) and regenerating changelog/stats.

Adds a new Browsers capability: POST /browsers/{id}/curl exposed as client.browsers.curl(id, params) with new BrowserCurlParams/BrowserCurlResponse types and public exports/docs, plus accompanying (skipped) tests.

Updates managed auth connection field typing to include an optional hint on discovered fields, and relaxes project creation docs to remove the paid plan gating note. Dependency lockfiles are refreshed (e.g., brace-expansion bump).
