Support node_modules created with bun install --linker=isolated

[dylan-conway]

Bun v1.2.19 added support for isolated installs similar to pnpm. This install strategy puts packages in ./node_modules/.bun. For example, simple-git-hooks@2.13.1 would exist in ./node_modules/.bun/simple-git-hooks@2.13.1/node_modules/simple-git-hooks

This pr adds detection for .bun in getProjectRootDirectoryFromNodeModules

Walkthrough

Updated getProjectRootDirectoryFromNodeModules in simple-git-hooks.js to recognize Bun’s .bun installation layout and return the correct project root. Added a unit test in simple-git-hooks.test.js to validate Bun path handling alongside existing pnpm/deno cases. No changes to exported/public declarations.

Changes

Cohort / File(s)	Summary
Root path resolution logic simple-git-hooks.js	Extend project root detection: handle Bun’s .bun path segment (slice path up to .bun), placed before existing .store handling. No API changes.
Unit tests simple-git-hooks.test.js	Add test covering Bun isolated linker path to ensure correct root resolution (var/my-project from .bun/.../simple-git-hooks).

Poem

I twitch my ears at Bun’s new trail,
Through .bun burrows I will not fail.
Hop-hop, the root is found with glee,
From nested nodes to project tree.
Carrot-commit, tests all run—
A tidy warren, Bun by Bun. 🥕🐇

simple-git-hooks.test.js (1)

76-82: Add a companion Bun test (without trailing /node_modules/simple-git-hooks) for parity with pnpm

You already cover the full Bun path; consider also testing just .../node_modules/.bun/simple-git-hooks@<version> like we do for pnpm. This guards against regressions and asserts the function works when given the package-dir path itself.

Apply this diff to add the extra test:

       it("return correct dir when installed using bun with --linker=isolated", () => {
         expect(
             simpleGitHooks.getProjectRootDirectoryFromNodeModules(
                 `var/my-project/node_modules/.bun/simple-git-hooks@${packageVersion}/node_modules/simple-git-hooks`
             )
         ).toBe('var/my-project');
       })
+      
+      it("return correct dir when installed using bun with --linker=isolated (package dir only)", () => {
+        expect(
+            simpleGitHooks.getProjectRootDirectoryFromNodeModules(
+                `var/my-project/node_modules/.bun/simple-git-hooks@${packageVersion}`
+            )
+        ).toBe("var/my-project");
+      });

117-120: Bun isolated linker support: logic and placement look correct

The .bun detection mirrors existing .pnpm/.deno handling and is correctly placed before the .store check. The slice up to indexOfBunDir - 1 resolves the proper project root for paths like .../node_modules/.bun/<pkg>@<ver>/node_modules/<pkg>. LGTM.
