v4.1.2

A payload reliability patch. Fixes a helper crash ~5 seconds after install
rejection on firmware 10.xx, and adds Polish language support.

• Fixed: helper dies after install rejection on FW 10.00+ (issue #152).
  The payload's install-init authid threshold was fw_major >= 11 — use the
  SYSTEM authid only on FW 11+, ShellCore everywhere below. But FW 10.xx
  has the same SYSTEM-authid gate for sceAppInstUtilInitialize: calling it
  under ShellCore leaves Sony's installer daemon (IPMI) half-wedged. The
  immediate InstallByPackage returns 0x80B2116F, and roughly 5 seconds
  later Sony's installer watchdog SIGKILLs our process — exactly the
  "helper dies after I click install" symptom in the bug bundle. The threshold
  is now fw_major >= 10, matching what the standalone DPI daemon already
  does on all firmwares. Users on FW 10.xx+ who push the updated payload from
  Connection → Send payload will stop seeing the post-reject crash.
• Fixed: outdated "Connect to your PS5" description (issue #208). The
  connection-screen blurb still said the helper stays loaded only until rest
  mode — which was true before the 4.1.0 auto-reconnect release but reads as
  stale now. Rewritten to point at the auto-reconnect toggle (on by default).
• New: Polish (Polski) language support. Thanks @heni0xyz for the
  contribution. Selectable from the language picker; the completeness test
  now covers pl alongside the other 18 locales.
