Show onboarding when config directory is missing

[muescha]

Summary

Show onboarding when the configured configuration directory is missing.

Problem

If the saved configuration directory does not exist, startup logs an error and returns early. Because onboarding had already been marked as completed, the onboarding window is not shown and the user cannot choose a new configuration path.

Fix

• Mark onboarding as incomplete when the configuration directory is missing.
• Also mark onboarding as incomplete when the configured init.js file is missing.
• Open the onboarding window when the onboarding state changes back to incomplete.
• Add regression tests for missing config directory and missing config file.

Testing

Focused ManagerManagerTests passed with xcodebuild test for the Development scheme on macOS, using CODE_SIGNING_ALLOWED=NO.

Greptile Summary

The PR restores onboarding when startup or reload finds that the configured directory or init.js is missing.

• Resets the persisted onboarding-completion state on either missing-path condition.
• Observes that state in the SwiftUI app and opens onboarding when it becomes incomplete.
• Adds focused manager tests for missing directories and files.
• Mirrors update, reload, and console actions in the application menus.

Confidence Score: 5/5

The PR appears safe to merge, with the missing-configuration recovery behavior covered by focused manager tests.

The changed manager paths persist an incomplete onboarding state when configuration resources are absent, and the application observes that state to present the existing onboarding window; no concrete blocking or independently actionable non-blocking issue remains.

Important Files Changed

Filename	Overview
Hammerspoon 2/Lifecycle/Hammerspoon_2App.swift	Opens the singleton onboarding window when completion becomes false and adds application-menu entry points for existing actions; no actionable defect identified.
Hammerspoon 2/Managers/ManagerManager.swift	Marks onboarding incomplete when either the configured directory or file is missing, matching the stated recovery behavior.
Hammerspoon 2Tests/ManagerTests/ManagerManagerTests.swift	Adds isolated regression coverage for both missing-path cases and updates onboarding setup for the expected template resources.
