Pull request overview

This pull request adds detection for prek installations made via the standalone installer, enabling the tool to provide appropriate update instructions based on how it was installed. The PR adds a new StandaloneInstaller variant to the InstallSource enum and implements detection logic using the AxoUpdater receipt system.

Changes:

Added StandaloneInstaller variant to the InstallSource enum
Implemented receipt-based detection for standalone installer installations using AxoUpdater
Added corresponding update instructions ("prek self update") and description text

Comments suppressed due to low confidence (1)

crates/prek/src/install_source.rs:1

The import of axoupdater::AxoUpdater should be conditional on the self-update feature, just like its usage. Currently, this import will cause a compilation error when the crate is built without the self-update feature because axoupdater is an optional dependency.

The import should be changed to:

#[cfg(feature = "self-update")]
use axoupdater::AxoUpdater;

use std::ffi::OsStr;

crates/prek/src/install_source.rs

+    fn is_standalone_installer() -> anyhow::Result<bool> {
+        use axoupdater::AxoUpdater;
+
+        let mut updater = AxoUpdater::new_for("prek");
+        let updater = updater.load_receipt()?;
+        Ok(updater.check_receipt_is_for_this_executable()?)


The new standalone installer detection functionality lacks test coverage. The existing test suite has comprehensive coverage for Homebrew detection and unknown paths, but there are no tests for the new StandaloneInstaller variant or the is_standalone_installer() method.

Consider adding tests that verify the standalone installer detection behavior, including cases where the receipt is found and valid, not found, or invalid. This is especially important given that the detection logic differs from the path-based Homebrew detection.
