v1.0.1: fix client crash when joining servers that verify players before login completes

CrowBar v1.0.1

A bugfix release for the Minecraft 26.1.x and 26.2 Fabric builds. Clients running CrowBar 1.0.0 could crash out of the world immediately after connecting to servers that hold players in a verification phase before the login handshake finishes.

Fixed

• Fixed a crash on join (NullPointerException in CrowBarState.checkXpGain) that disconnected the client from servers running anti-bot or verification plugins.
  • Player.gameMode() is null between the moment the client enters the level and the server's first game mode packet. Servers that hold players in a "please do not move" verification phase tick the player during that window, so CrowBar's experience-gain check dereferenced a null game mode and threw a ReportedException from Level.guardEntityTick, tearing down the level session.
  • The game mode is now checked for null before the survival test, so the experience-gain tracker simply skips ticks that happen before the server assigns a game mode.

Affected Builds

• Minecraft 26.1.x (Fabric) and Minecraft 26.2 (Fabric) carried the bug and are fixed.
• The NeoForge builds and the 1.21.x Fabric builds never read the game mode in the experience-gain check and were never affected; they are rebuilt at 1.0.1 so every listing stays on one version.

Testing

• Verified the 26.1.x and 26.2 Fabric subprojects compile and package cleanly with the guard in place.
• Confirmed no other code path in any loader build dereferences Player.gameMode().
