List an agent's prompt/config version history
Return the agent’s immutable prompt/config checkpoint history — system prompt, model, sampling knobs, tools, knowledge-base bindings, safety config, per-conversation cost cap, branch/label provenance, and timestamps per version — newest first, plus the distinct branch names in use. Cursor-paginate with ?cursor=<version_number> (from the previous page’s next_cursor), ?limit (1-200, default 50), and narrow to one experiment line with ?branch=<label>. Use it to pick a rollback target before promoting. 404 when the agent does not exist.

Headers
Sandbox opt-in for Clerk-session-authenticated requests. Set to true to route the call through the test-mode pipeline: no real provider delivery, no credits deducted, response meta.test_mode: true. Ignored for live API keys (dv_live_sk_*) — server-to-server clients must use a test-prefixed key (dv_test_sk_*) to exercise sandbox. Test-prefixed keys unconditionally enable sandbox regardless of this header.
