CodeNomad's per-workspace instance proxy was upgraded and now only
serves opencode v2 /api/* routes; the v1 /session/... routes 403, which
broke all notifications.
- Discovery: GET {api}{proxyPath}/api/session (v2 {data,cursor} envelope)
instead of GET {base}/session; sessions filtered by location.directory
and the max time.updated entry is picked.
- Send: POST {api}{proxyPath}/api/session/{sid}/prompt with a {text}
body instead of POST {base}/session/{id}/message with {parts:[...]}.
- v2 returns 2xx immediately, so the 15 s read-timeout-as-delivered
branch is kept only as a harmless safety net.
- Updated the spec to the v2 routes/body/envelope (incl. a
directory-filter assertion) and kept AGENTS.md in sync.
