CallVault v2.4.4-rc1

Test build — not a release. The in-app updater will not offer it; install it by hand over 2.4.3. When the final 2.4.4 is published, the in-app updater will offer it to this build as usual.

• App calls record on vivo and iQOO phones. 2.4.3 fixed the other person's side; this build also opens your own microphone the way vivo's Android needs, so WhatsApp, Telegram and other app calls record both sides.
• Phone calls on vivo use CallVault's own recording again, including Resilient recording, instead of falling back to the slower backup path.
• An app call that could not start recording no longer says the other app blocked it.

Everything else is 2.4.3. If something is wrong, turn on Settings → Debug → Debug logs, make one app call, and share the log from Settings → Debug.
