Stryker V6.0.1 [Hotfix]

Fixed

• Data loss when upgrading from pre-4.5R installs. The guard before deleting the old
  chroot required all four of its mounts to be present, so a partly detached chroot — and
  the pre-4.5R layout, which binds the whole /sdcard at <root>/sdcard instead of
  <root>/sdcard/Stryker — read as "nothing mounted". The delete then followed the live
  bind into internal storage. Mount detection is now layout-agnostic, every recursive
  delete is gated on it and fails closed when /proc/mounts cannot be read, and killroot
  detaches both bind layouts plus anything else left under the chroot.
• Install no longer proceeds after a failed cleanup, instead of extracting the rootfs
  over a live mount.
• "no usable tar" on devices without root. A missing su was masked by an echo stub,
  so every probe returned nothing and the installer blamed tar. Missing root is now named
  as the cause, and the pre-check no longer starts a chroot install without root — it
  offers the rootless engine instead of a dead end.
• Captured handshakes never reached the captured folder. 6.0 replaced a root-shell
  move with an app-side directory listing, which does not share root's view of shared
  storage. Falls back to a mount-master root shell.
• Wordlists were not listed. Shared storage was listed through a root shell whose view
  of /storage/emulated/0 differs from the app's; it is now listed by the app in both
  engines, and the Wi-Fi wordlist picker follows the rootless share.
• Terminal crashed on launch with Cannot create component config directory. A stale
  file or dangling symlink made exists() report absent while mkdirs() failed. The path
  is now repaired, and a config-directory failure falls back to built-in defaults instead
  of killing the activity.

Changed

• CI builds again: lint no longer aborts the library modules (thanks @kylefmohr, #40).
