feat(cli): Agent Mode bootstrap + claim flow (Python + Node) (#5123)

+"""Detect whether the CLI is being invoked from inside an AI-agent context.
+
+Used by `mem0 init` to auto-enter Agent Mode (Rule 3 bootstrap) when an
+agent runtime env var is present. The return value is a context **trigger
+only** — the canonical agent identity is self-declared by the agent via
+``--agent-caller <name>`` (Proof Editor-style) and never sniffed from env
+vars to fill the ``agent_caller`` field on the APIKey row.
+
+Returns a short name or None. The list is curated, not exhaustive — env
+vars we don't recognise fall through to None (caller treated as
+non-agent). Honest reporting depends on ``--agent-caller``; this list is
+just enough to enable the zero-friction auto-bootstrap UX.
