fix: set DEPS_CLJ_TOOLS_DIR for sandbox HOME mismatch

Inside the awf sandbox $HOME is /root (runs as root), but the
mount maps /home/runner/.deps.clj into the container at that same
host path. bb's deps.clj uses $HOME/.deps.clj/ by default, so it
looks in /root/.deps.clj/ and misses the mount. Setting
DEPS_CLJ_TOOLS_DIR to the absolute /home/runner/.deps.clj path
via GITHUB_ENV ensures bb finds the tools jar regardless of $HOME.

Also removed debug logging from previous iteration.
