Hotfix for Claude Code v2.1.117+
The PreToolUse hook installed by graphify claude install was silently broken on Claude Code v2.1.117+ because dedicated Grep and Glob tools were removed — searches now go through Bash. The hook never fired, meaning the graph context reminder was never injected.
Fix: Hook matcher changed from Glob|Grep to Bash. The hook now reads the tool input JSON from stdin and pattern-matches on the command string, firing only on search-like calls (grep, rg, find, fd etc.) — not on every shell command.
Upgrade: pip install --upgrade graphifyy && graphify claude install
Closes #578
