fix(rgtv-cli): pin ureq to 2.x to match existing code

The crate was bumped to ureq 3.x but src/main.rs still calls
AgentBuilder, Error::Status/Transport, and RequestBuilder::set — all
removed in 3.0. cargo check fails with E0433/E0599 across rgtv-cli's
HTTP client. Pinning back to 2.x unblocks CI; a follow-up should
migrate the code to ureq 3.x and unpin.
