Fixes https://github.com/zed-industries/zed/issues/63672 OpenCode Go now requires the `x-opencode-session` header on every model request. Zed previously sent the header only when a request already had a thread ID, so inline assistance, terminal assistance, and other standalone requests could omit it and risk rejection. This change makes the OpenCode provider add the header to every request. Existing thread and assist session IDs are reused when available. Standalone requests receive a generated non-empty ID. Thread title and summary requests now carry the thread ID so related requests keep the same session scope. The change also adds tests for missing, empty, and invalid IDs, plus a wire-level test that verifies the header reaches the HTTP client. The provider test file stays separate so the implementation remains under 1,000 lines. Testing: - `cargo fmt --all -- --check` - Focused OpenCode, thread summary, and thread title tests - `cargo check -p agent_ui -p sidebar` - `GITHUB_ACTIONS=1 ./script/clippy -p language_models` - `git diff --check` Release Notes: - Fixed OpenCode Go requests that could fail when Zed omitted the session header. --------- Co-authored-by: Kirill Bulatov <kirill@zed.dev> Co-authored-by: Christopher Biscardi <chris@christopherbiscardi.com>
