Raise default nofile limit to fix silent game launch failures

Wine/Proton's winediag channel logs 'Too many open files' when the common Linux default (1024–4096) is hit, which can cause a game to silently fail to launch with no other visible error in Steam's own console. Confirmed via a real Path of Exile 2 launch failure, fully resolved by raising the limit via a PAM limits.d drop-in.

+# Raises the default open-file limit system-wide.
+#
+# The stock Linux default (1024, or ~4096 on some distros) is too low for
+# some modern games and other heavy-I/O applications — Wine/Proton's own
+# winediag channel explicitly flags "Too many open files" when this is
+# hit, which can manifest as a game silently failing to start with no
+# other visible error. Confirmed via a real Path of Exile 2 launch
+# failure that was resolved entirely by this change.
+#
+# Shipped as a drop-in (rather than editing limits.conf directly) so it
+# can be overridden or removed cleanly without touching a shared file.
