feat(cli): add mem0 whoami + mem0 agent-rush subcommands

Mirrors implementation across Node (TypeScript) and Python CLIs.

mem0 whoami:
  Prints the agent's default_user_id from local config — the AGENTRUSH
  leaderboard identifier. Used by players to cross-verify their row.

mem0 agent-rush <add|search>:
  Wraps the platform's /v1/agent-rush/{memories/, memories/search/}
  endpoints. Project routing is implicit (server-resolved); no flags.
  Pretty-prints platform error codes into actionable hints (e.g.
  agentrush_search_first → "Run 3 'mem0 agent-rush search' commands
  before adding.").

Adds X-Mem0-Mode: agent-rush header for telemetry. Reuses existing
agent-mode API key from config; surfaces a graceful error if config
is missing or the key was created outside agent-mode.
