fix(cli): mem0 init --agent now triggers bootstrap (Node) + created_via parity

External sandbox audit (Sandbox E2E Test Report 2026-05-13) surfaced
two CLI issues.

1. Node — `mem0 init --agent` silently falls through to the non-TTY
   error when no agent env var is set. Commander resolves the
   program-level `--agent` alias (for --json) before init's own
   `--agent`; init's opts.agent stays false. Fix: enable Commander's
   positional options so flags AFTER a subcommand belong to that
   subcommand. Now `mem0 --agent <cmd>` is the JSON-output alias and
   `mem0 init --agent` is the Agent Mode bootstrap flag.

   The Python side already had an argv preprocessor doing the
   equivalent; this brings Node to parity using Commander's built-in
   mechanism (cleaner than mirroring the preprocessor).

   Verified: `mem0 init --agent` with bogus MEM0_BASE_URL now hits the
   bootstrap fetch and surfaces a network error (proving it reached
   bootstrap_via_backend), where before it printed "Non-interactive
   terminal detected" and never made an HTTP call.

2. Both — `config.platform.created_via` was inconsistent: set to
   "agent_mode" / "email" on the agent/claim paths but left empty on
   normal email signup and api-key paths. Now all four paths set it:
   "agent_mode" (bootstrap), "email" (OTP signup or claim), "api_key"
   (--api-key flag or interactive prompt). Downstream consumers can
   reliably filter on created_via==value.
