Mega Man X4 Recompiled — v0.1.1-coop-playtest.15

Two-player X + Zero co-op for Windows and Linux. Both netplay peers must update.

• Storm Owl progression: P2 can now reach the second part of the stage while
  P1 is dead. The normal transition with both players alive also works.
• X's armor colors: collecting armor in Zero's campaign keeps X's correct
  palette, including after opening and closing the pause menu.
• Web Spider capture: a web that kills one player now releases instead of
  pulling in and damaging the surviving partner.

Unified cameras and Stacked lifebars remain the defaults; Split is experimental.
The co-op door options and optional doubled boss health remain available in Mods.

Diagnostics remain enabled by default for fresh installs. If you previously
disabled them, enable Mods → Playtest Diagnostics → Input Display and Recording.
Look for REC while playing. After reproducing a bug, quit normally and zip
the complete saves/diagnostics folder beside the executable or AppImage.

Keep normal memory-card saves for campaign progress; use save states made with
this release. Windows and Linux production checks pass. These fixes were
reproduced and checked in native gameplay; outstanding reports retain their
status in the numbered checklist.
