remove redundant marauder wrappers and anthropic dependency

memory.py and marauder_cart.py were subprocess wrappers around marauder
CLI — redundant now that the opencode chat agent has native EEMS tools.
Also remove custom TOOLS dict, EEMS context injection at session start,
marauder_cart.create() in calibration_done, and anthropic dep/env vars.
Inline slug() as _slug() in calibration.py.

app/calibration.py
