fix(run.sh): use MCP_GATEWAY_AGENT_ID with deprecated fallback for MCP_GATEWAY_API_KEY

[Copilot]

run.sh was checking for the deprecated MCP_GATEWAY_API_KEY variable, causing a misleading "API authentication disabled" warning for users who correctly set MCP_GATEWAY_AGENT_ID per current documentation.

Changes

• run.sh: Replace the MCP_GATEWAY_API_KEY check with the same pattern already used in run_containerized.sh:
  • No vars set → warns MCP_GATEWAY_AGENT_ID not set, API authentication disabled
  • Only MCP_GATEWAY_API_KEY set → deprecation warning + auto-maps to MCP_GATEWAY_AGENT_ID
  • Updates the "For production, set:" hint to reference MCP_GATEWAY_AGENT_ID

# Before
if [ -z "$MCP_GATEWAY_API_KEY" ]; then
    log_warn "MCP_GATEWAY_API_KEY not set, API authentication disabled"
    warnings=$((warnings + 1))
fi

# After
if [ -z "$MCP_GATEWAY_AGENT_ID" ] && [ -z "$MCP_GATEWAY_API_KEY" ]; then
    log_warn "MCP_GATEWAY_AGENT_ID not set, API authentication disabled"
    warnings=$((warnings + 1))
elif [ -z "$MCP_GATEWAY_AGENT_ID" ] && [ -n "$MCP_GATEWAY_API_KEY" ]; then
    log_warn "MCP_GATEWAY_API_KEY is deprecated; please rename it to MCP_GATEWAY_AGENT_ID"
    export MCP_GATEWAY_AGENT_ID="$MCP_GATEWAY_API_KEY"
fi

Pull request overview

This PR updates run.sh’s optional environment validation to prefer MCP_GATEWAY_AGENT_ID (as documented) while still accepting the deprecated MCP_GATEWAY_API_KEY as a fallback, eliminating a misleading warning for correctly configured users.

Changes:

• Switch run.sh to check MCP_GATEWAY_AGENT_ID first, with a deprecated fallback mapping from MCP_GATEWAY_API_KEY.
• Update the “For production, set:” hint to reference MCP_GATEWAY_AGENT_ID instead of MCP_GATEWAY_API_KEY.
