GCP OS Login doesn't honor /etc/group changes for SSH sessions,
so analyst can't read /opt/data-analyst/.env even after usermod.
Wrapper now reads .remote_query.env from scripts dir (dataread group),
falls back to .env for admin users. The env file contains only
non-secret BQ config (project ID, location, data dir).
Analyst user (foundry_e_psimecek) couldn't access /opt/data-analyst/.
Added to data-ops group on server.
New scripts/remote_query.sh wrapper handles env setup (PYTHONPATH,
CONFIG_DIR, .env) so agents use simple:
ssh alias 'bash ~/server/scripts/remote_query.sh --sql "..." --format table'
Updated claude_md_template.txt to use wrapper instead of raw commands.
