2.2.5-alpha

Adds X1 Boss Rush and fixes several co-op camera and transition bugs.

• Boss Rush: a new title-menu option for endless fights against two different Mavericks at once. Replacements come from a shuffled roster of all eight bosses. Uses your existing solo/co-op setting, starts with all X1 weapons and four full shared Sub Tanks, drops a large health pickup per defeat, and saves your high score locally. The run ends when the last player dies.
• Storm Eagle: fixes the lift freeze when scene ownership transfers to the other player.
• Armored Armadillo: keeps each player's authored camera bounds, prevents the reproduced false pit death on solid ground, and relocates both players together at the stage's coordinate wrap.
• Rendering: fixes hidden sprite strips appearing in a distant player's view and Spark Mandrill's fading light position when the players are at different heights.
• Diagnostics: new replays include each player's camera-region history. Existing replay formats and older save states remain supported.

See the Boss Rush guide and screenshots.

The merged changes passed recorded-input regressions for both driver seats, renderer checks, save/rewind checks, diagnostic replay acceptance, and desktop CI. Release packaging checks cover the Windows ZIP and Linux AppImage.

Issue #110 remains open: Penguin's cave/camera reports need gameplay confirmation, and persistent missing Octopus fish or Chameleon birds have not been isolated. A separate Mandrill process crash was not reproduced.
