v0.4.0

0.4.0

• whoami: show the logged-in account and its tenant affiliation (if the account was registered via a tenant's invite code), using the existing /api/me endpoint. login now prints this automatically right after signing in.
• Update check: update-notifier checks npm for a newer version at most once per 12h and prints a notice — no more silently running stale versions.
• --version now reads from package.json at runtime instead of a hardcoded string in index.ts (the two had already drifted out of sync once before 0.3.0).
