add context window monitor
Writes the current context window to logs/current_context_window (uses a symlink to a session ID). This PR was unfortunately generated by a different LLM and did a ton of superficial reformating, it's actually a fairly small and benign change, but I don't want to roll back everything. Hope that's ok.
