Updating build.sh to allow for ONLY_VERSION and DRY_RUN - so we can build specific builds, or print out version info for specific builds.

AGENTS.md

+# CreatureChat Agent Instructions
+
+See **build.sh** for commands and supported Minecraft/Fabric versions.
+
+## To Build
+Run this to build **all versions**:
+
+```bash
+./build.sh
+````
+
+Build a **specific version** only:
+
+```bash
+ONLY_VERSION=1.20.1 ./build.sh
+```
+
+Preview the build steps without making changes:
+
+```bash
+DRY_RUN=1 ./build.sh
+```
+
+Or for a specific version:
+
+```bash
+ONLY_VERSION=1.20.1 DRY_RUN=1 ./build.sh
+```
+
+## Notes
+
+* This script modifies `gradle.properties` and `fabric.mod.json`
+* Run only when you're ready to test builds
