fix(mke-wintertodt): preserve warm gear and accept hammer variants

[RLitePlus]

Problem

• Automatic gear selection could replace warm clothing with cold armour, including rune equipment, graceful pieces, and dragon defenders.
• Equipping an axe could reduce the player below four warm items.
• Hammer detection rejected Imcando hammer variants.

Solution

• Select accessible warm clothing through the shared RuneLite warm-item collection.
• Reject cold non-weapon gear and preserve four equipped warm items.
• Keep the axe in inventory when equipping it would reduce warmth.
• Recognize standard, main-hand Imcando, and off-hand Imcando hammers.
• Propagate gear and inventory setup failures.

Additional notes

Bump version from 2.2.1 to 2.2.2

• Local policy regression passed for the reported and sibling warm outfits, cold fallback gear, and hammer variants.
• Bank-only live acceptance passed in 78.4 seconds with four warm items, one hammer, an inventory axe, no movement, and no duplicate withdrawal.
• Dynamic production-source compilation and git diff --check passed.
• Gradle compilation could not start because the required Adoptium Java 11 toolchain is unavailable; this repository exposes no checkstyle task.

Maintainer base sync and required follow-up version bump pushed in 9df4e83: merged the now-current development (including MKE Wintertodt 2.2.2 from #548) and advanced this plugin to 2.2.3. The warm-gear and hammer behavior is unchanged. Fresh ./gradlew clean build -PpluginList=MKE_WintertodtPlugin and git diff --check passed on the merged tree. Awaiting the new expected CI run.
