All 5 sessions endpoints, with request fields and access notes.

Request fields and access notes below are partial. Additional constraints and permissions may apply. Prefer the corresponding MCP tool and schema where available.

Query field names (types and requiredness not specified here): `include_inactive`.

## POST /v1/sessions

List sessions or register an agent identity, depending on HTTP method.
