[Personal WP] Install my-apps on existing personal sites

[akirk]

What?

• Adds a shared Personal WP App Launcher blueprint helper.
• Automatically checks existing personal sites for the my-apps plugin file and installs it when missing.
• Persists a migration marker after the plugin is present and syncs that marker across tabs.

Why?

Older Personal WP sites predate the default my-apps plugin. This equips those sites without reinstalling when users already have the plugin.

Testing

• npm exec nx test playground-personal-wp -- --run
• npm exec nx typecheck playground-personal-wp
• npm exec nx lint playground-personal-wp

Pull request overview

Note

Copilot was unable to run its full agentic suite in this review.

Adds a shared “my-apps” (App Launcher) blueprint helper and introduces a one-off migration flow to ensure older Personal WP sites have the plugin installed, persisting and cross-tab syncing a migration marker.

Changes:

• Add appliedMigrations to site metadata and include it in cross-tab metadata sync.
• Introduce personalwp/my-apps helpers for blueprint URL creation and plugin presence checks (with tests).
• Add an automatic migration in the viewport to install my-apps when missing and record the migration timestamp.

Addressed the Copilot review comments:

• Track my-apps migrations in progress per site with a Set instead of a single slug.
• Mark migrations through a dedicated metadata thunk so appliedMigrations is merged from current Redux state.
• Deep-merge appliedMigrations in the metadata reducer for cross-tab updates.
• Narrow the migration effect dependencies to primitive site fields.
• Pin the my-apps git:directory resource to commit 4e2c6f58b49bc8ccb88c6413c49929f076f80788.
