Reduce token count

Adding CE mcp eats up a decent chunk of claude's memory:

```
MCP tools · /mcp
└ mcp__compiler-explorer__compile_check_tool (compiler-explorer): 1.5k tokens
└ mcp__compiler-explorer__compile_and_run_tool (compiler-explorer): 1.8k tokens

compared to GH's MCP where each command is 500-600 tokens
