Subject: [PATCH] opencode: fix Bash tool command execution error on Linux

Previously, prompting the LLM to execute CLI commands using the Bash tool on Linux
would fail with the following error:

  Error [ERR_DLOPEN_FAILED]: libstdc++.so.6: cannot open shared object file: No such
  file or directory

This commit resolves the issue by ensuring libstdc++.so.6 is included
in LD_LIBRARY_PATH.

Fixes: #432051
