fix: remove settings.json that was incorrectly force-added

This file was added with -f despite .claude/ being in .gitignore.
When the repo is used as a crew workspace, this file shadows the
proper crew-level settings at crew/.claude/settings.json.

Removing it allows Claude Code to find the correct settings by
walking up the directory tree.
