2.0.0b7 (2026-06-28)

Container protocol version 2.0.0 support: added the platform identity header constants x-agent-user-id (USER_ID) — the global, cross-agent per-user partition key — and x-agent-foundry-call-id (FOUNDRY_CALL_ID) — the opaque per-request call identifier — to the _platform_headers module.
Added FOUNDRY_AGENT_ID environment variable support exposing the agent's stable GUID via AgentConfig.agent_guid and the resolve_agent_guid() helper.
Added a request-scoped platform context: FoundryAgentRequestContext, get_request_context(), set_request_context(), and reset_request_context(). Protocol packages bind the inbound per-request call ID and user ID so that handler code (and the SDK HTTP pipeline) can read them. FoundryAgentRequestContext.platform_headers() builds the headers to forward on outbound Foundry 1P calls — the per-request call ID only; x-agent-user-id is not forwarded (it is not accepted/trusted by 1P services and is used only for container-side state partitioning).

Replaced the x-agent-user-isolation-key / x-agent-chat-isolation-key header constants (USER_ISOLATION_KEY / CHAT_ISOLATION_KEY) with x-agent-user-id (USER_ID) and x-agent-foundry-call-id (FOUNDRY_CALL_ID) per container protocol version 2.0.0.
