Implements the subset of the hosted mem0 platform API that mem0ai==2.0.2
MemoryClient calls, so MemoryClient(host=..., api_key=...) works against this
server. Verified end-to-end (construct/add/search/get_all/get/history/update/delete).
- platform_compat.py: GET /v1/ping/ (returns non-empty org_id/project_id, which
the SDK's Project init requires), POST /v3/memories/{add,search}/,
POST /v3/memories/ (paginated get_all), /v1/memories/{id}/ item ops, and
GET /v1/entities/ -- all mapped onto the existing mem0_manager.
- auth.get_current_user_platform: accepts Authorization: Token (mem0 SDK),
Bearer, or X-API-Key.
- main.py: include the platform router; remove the /v1/memories* aliases added
in ea07a82 (the SDK uses /v3 and trailing-slash /v1/memories/{id}/, not those
paths); keep /v1/chat/completions and the native /memories* routes.
- docker-compose: run uvicorn with --proxy-headers --forwarded-allow-ips=* so the
proxy's https scheme is honoured. This stops trailing-slash 307 redirects from
downgrading https->http and dropping the Authorization header -- the actual
cause of the reported "POST auth broken" symptom (auth was never broken).
- test_sdk_compat.py: end-to-end MemoryClient round-trip against the server.
