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

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

 Same syntax as `.gitignore`. You can keep a single `.graphifyignore` at your repo root — patterns work correctly even when graphify is run on a subfolder.

+- **Hook fix for Claude Code v2.1.117+** — the PreToolUse hook now matches on `Bash` instead of `Glob|Grep`. Claude Code v2.1.117 removed dedicated Grep/Glob tools; searches now go through Bash. The hook inspects the command string and only fires on search-like calls (grep, rg, find, fd etc.), so it does not trigger on every shell command.

 ## What's new in v0.5.1
 
 - **Node ID collision fix** — files sharing the same name in different directories (e.g. two `utils.py` files) now get unique IDs by prefixing the parent directory name.
