Firmachain v0.5.1-patch Official Release

Overview

The v0.5.1-patch resolves an issue #20 where temporary WASM directories (e.g., /tmp/.firmachainXXXXXXX) were created on every firmachaind execution and never removed. Over time, this caused inode exhaustion and unnecessary disk usage.

This patch ensures that CosmWasm’s temp directories are properly cleaned after each command execution.

The patch is non-consensus breaking and requires no governance proposal. Nodes may safely upgrade at any time.
