Fix PreToolUse hook for Claude Code v2.1.117+ (Glob|Grep → Bash matcher)

Browse Source 
Grep and Glob tools removed in CC v2.1.117; searches now go through Bash.
Hook now reads stdin tool_input and pattern-matches on search commands.
Uninstall/reinstall handles both old and new matcher for clean upgrades.

Closes #578
