The model field on agent create accepts {id, speed}, not
{type: "model_config", id, speed}. Aligns with the shape documented
elsewhere in managed-agents-core.md and the request body table.
Add shared/managed-agents-memory.md covering the Memory Stores public
beta under managed-agents-2026-04-01: object model (memstore_/mem_/
memver_), create + seed, attach via resources[] at session-create time,
FUSE mount at /mnt/memory/<store>/, host-side CRUD with create-by-path
vs update-by-id, content_sha256 preconditions, and versions/redact.
Wire it through all cross-references: SKILL.md beta-headers namespace
and reading guide; api-reference SDK method rows, delete/archive quirks
bullet, AddResource note, and three new endpoint sections; core.md
architecture diagram and resources[] enumerations; environments.md
Resources intro; overview.md beta-headers table, Reading Guide row, and
archive-is-permanent bullet.
