List structured memories with optional filters. Requires `read` scope. Without
`scope`, returns only `global` plus the authenticated caller's `user`
namespace. The public endpoint accepts `global`, `workstream`, and `user`;

A memory's identity is the tuple `(name, scope, scope_id)`. Saving a memory
with the same identity upserts -- updating content while preserving the ID.
### Coordinator scope
### Inherited target and coordinator scope
Coordinator sessions are isolated to a single scope: `coordinator`, keyed by
the coordinator's creator `user_id`. It is durable -- every coordinator
session the same user runs (including concurrent ones) shares one
orchestration namespace, so procedures and lessons survive close/reopen.
Name-based operations use one inherited target when `scope` is omitted:
- An attached active project selects `project` for `save`, `get`, and
`delete`.
- Read-only project access permits `get`, but `save` and `delete` fail. They do
not fall back to a broader namespace.
- Without a project, interactive sessions select `global`; coordinator
sessions select `coordinator`.
A valid explicit scope selects exactly that scope. `search` and `list` are the
only actions that span every visible scope when `scope` is omitted.
Each coordinator's private `coordinator` namespace is keyed by the acting
user's `user_id`. It is durable -- every coordinator session that user runs
(including concurrent ones) shares one orchestration namespace, so procedures
and lessons survive close/reopen.
Isolation is bidirectional and enforced by session kind, not by secrecy of
the scope id:
- A coordinator session can read and write **only** `coordinator`-scope rows.
It never sees `global`/`workstream`/`user` memories, so content written by
interactive sessions (which routinely ingest untrusted MCP/attachment
output) cannot reach a coordinator's system message.
- A coordinator session sees its acting user's `coordinator` scope and, when
attached, the shared `project` scope. It never sees
`global`/`workstream`/`user` memories.
- Interactive sessions -- including a coordinator's own children, which share
its `user_id` -- are rejected from the `coordinator` scope on every memory
action. Children cannot plant rows the parent coordinator would read.

Relevant memories are included in the system prompt on startup.
- **What it does**: Manages structured persistent memories in the database.
Memories persist across sessions, have a type classification, and live in a
role-specific visible scope. Unscoped `save`/`get`/`delete` resolve to one
target: the attached active project, otherwise `global` for an interactive
session or `coordinator` for a coordinator. Read-only project access permits
`get` but makes `save`/`delete` fail without falling back. A valid explicit
scope selects exactly that scope. Unscoped `search`/`list` cover all visible
scopes; use the displayed scope when following a result with `get` or
`delete`.
