Browserbase has no DELETE endpoint for sessions. The correct API is
POST /v1/sessions/:id with body { status: "REQUEST_RELEASE" }. The old
DELETE call returned an error that was silently swallowed, causing every
session to leak until the 30-min idle timeout.
Fixed in both Node.js (src/browser.ts) and native Rust
(cli/src/native/providers.rs) paths.
