Copyosity 0.9.6 — in-app update log

Adds an Update log in Settings → Updates: every update step (launch auto-check, manual check, download, install, relaunch) and the full error text is recorded, with Copy/Clear. If an update fails, open it, copy the log, and send it — it shows exactly what went wrong.

The full update flow (check → download → install → relaunch) is verified working with clean tarballs.
