test: compare the statusline copy path JSON-escaped in hooks.test.js

[Bettinho179]

What

tests/hooks.test.js failed on Windows at the #1032 assertion ("nudge must point at the config-dir copy, not the plugin cache").

Why

The statusline nudge embeds the script path in a JSON snippet (JSON.stringify(command)), so on win32 the backslashes are doubled (C:\\Users\\...\\ponytail-statusline.ps1). The assertion searched stdout for the raw path, so it never matched on Windows. Because it is a plain assert.ok in a top-level script, the failure also skipped every assertion after it (the broken-statusLine and spaced-path cases).

The hook output is correct; only the test was POSIX-only.

Change

Compare against the JSON-encoded form of the path: JSON.stringify(copyPath).slice(1, -1). On POSIX this is identical to the raw path, so behavior there is unchanged.

Checks

On Windows 11, Node 24:

• npm test: 125 pass, 0 fail, 2 skipped (main suite); 28/28 (pi-extension)
• node scripts/check-rule-copies.js: ok
• node scripts/check-versions.js: ok

Thanks! Checked it: on Windows the hook prints the path JSON-encoded, so the old check never matched and skipped the rest of the file; on macOS and Linux nothing changes. Merged.
