v1.7.1 — Minecraft 26.3 Release Support

This is the MCAI 1.7.1 stable release, fully compatible with the Minecraft 26.3 release (superseding the 26.3-pre-1 snapshot). It is the first stable release targeting the 26.3 release.

Changes

• Minecraft 26.3 release support: Upgraded from the 26.3-pre-1 snapshot to the 26.3 release (world 5023 / protocol 777 / Java 25).
• Fabric API upgrade: 0.161.0+26.3 (Fabric Loader ≥0.19.3; this release uses 0.19.5).
• Adapted to CommandSourceStack API changes: The constructor no longer takes textName/displayName. Use createCommandSourceStack() with chained withSource(), withPermission(), withPosition(), withRotation(), and withLevel() calls instead.
• Removed dead code: Deleted the KnowledgeBase class and its tests.
• Removed /aiclear command: The history-clearing functionality has been merged into /aireload.
• Relaxed AI response interception: Only raw commands are intercepted. AI may now output commands starting with / as plain text to explain syntax.
• System prompt updates: Added version-number mappings and improved Wiki search hit rate.
• CI improvements: Upgraded setup-java to v5 and fixed the Linux wrapper build.
