Live: local smoke commands

Export the needed provider key in the process environment before ad hoc live checks.

Safe media smoke:

pnpm apus infer tts convert --local --json \
  --text "Apus live smoke." \
  --output /tmp/apus-live-smoke.mp3

Safe voice-call readiness smoke:

pnpm apus voicecall setup --json
pnpm apus voicecall smoke --to "+15555550123"

voicecall smoke is a dry run unless --yes is also present; use --yes only when you intend to place a real call. For Twilio, Telnyx, and Plivo, a successful readiness check requires a public webhook URL - local/private loopback URLs are rejected because those providers cannot reach them.
