v0.5.2 — no real name in the example output

The example `windows` output carried a real Telegram contact's name instead of a made-up one -- captured live while measuring an early read (see CR-007) and never swapped for a placeholder. It has been in the bundled skill, and so in every published wheel, since 0.2.0. Replaced with a generic name everywhere it appeared (the skill and three docs). No behaviour changes.
