graphify hook status reports "not installed" on husky 9 repos (looks in .husky/_/<hook> wrapper, not .husky/<hook>) #987

Environment

• graphifyy 0.8.16 (pip)
• git 2.x with husky 9 (core.hooksPath = .husky/_)
• macOS Darwin 25.3.0, Python 3.11

Symptom

With graphify's post-commit/post-checkout hooks correctly installed (markers present in .husky/post-commit and .husky/post-checkout, hooks fire on commit/checkout, rebuild log confirms execution), graphify hook status reports:

post-commit: not installed (hook exists but graphify not found)
post-checkout: not installed (hook exists but graphify not found)

Root cause

Husky 9 sets core.hooksPath = .husky/_. _hooks_dir(root) in graphify/hooks.py correctly returns .husky/_ per the fix from #401. But husky's layout puts the wrapper there:

.husky/_/post-commit    → #!/usr/bin/env sh\n. "$(dirname "$0")/h"
.husky/post-commit      → actual user hook with `# graphify-hook-start` marker

_check() in hooks.py:296 opens hooks_dir / name = .husky/_/post-commit, which is the two-line husky shim. The marker isn't there, so status reports "not installed" even though the chain .husky/_/post-commit → .husky/_/h → .husky/post-commit is wired up and active.

Reproduction

git init demo && cd demo
pnpm dlx husky init   # or any husky 9 install
graphify hook install
graphify hook status  # reports "not installed" despite working hooks

Suggested fix

In _check(), when hooks_dir.name == "_" and hooks_dir.parent.name == ".husky", also check hooks_dir.parent / name for the marker before reporting "not installed".
