feat(whoami): consume account.me to populate user identity (#101)

The deployng `account.me` tRPC procedure has landed, so `deno deploy
whoami` can now identify the principal behind the token rather than
just listing reachable orgs.

- Calls `account.me` in parallel with `orgs.list` (no extra round
  trip).
- JSON output: `user` field is now populated for user-backed tokens
  (`{ id, name, email, avatarUrl, githubLogin }`) and `null` for
  org-scoped (`ddo_`) tokens. A new `tokenType` field carries the
  raw token type from the backend in both cases.
- Human output: the "Authenticated" line now names the principal
  (`@github-login`, falling back to email/name/id, or
  `org-scoped token (...)` for non-user tokens).

Existing agent consumers reading `authenticated` and `orgs[]` keep
working; only added fields.
