fix(cloud-agent): tolerate interrupt errors during claude session refresh

[tatoalo]

Problem

recently observer that a follow-up message reached the agent-server but was instantly aborted ("Operation aborted"`), and every subsequent message failed the same way (surfacing in the client as a queue failure).

claude adapter's refreshSession aborts the live query's AbortController, then awaits prev.query.interrupt() before installing the fresh controller/query

Changes

• wrap await prev.query.interrupt() in try/catch so tearing down the old query can't abort the swap. Keeps the abort-first ordering; brings the claude adapter to parity with codex (which works with the guard already)
