chore: archive A-WP-Notes v3.0.2 — minimalist parallel fork

Imports the v3.0.2 line of A-WP-Notes as it existed on M5 at:
  Local Sites/wordpress/public/wp-content/plugins/a-wp-notes/

This is a deliberately minimal parallel fork of the plugin, distinct
from the v1.2.0 line in ranger/a-wp-notes. It carries only the core
note-taking functionality:

  wp-notes.php                       — plugin bootstrap + admin UI
  inc/wp-notes-display.php           — note rendering
  inc/wp-notes-about.php             — About page
  inc/wp-notes-feedback.php          — feedback module
  inc/wp-notes-styles.php            — style enqueues
  inc/wp-notes-updater.php           — self-hosted updater stub
  inc/admin-bar.php                  — admin bar integration
  js/wp-notes-feedback.js            — feedback front-end
  js/Chart.js                        — charting (bundled)
  assets/wp-notes-banner.jpg         — plugin banner

The AI ecosystem (chat, personalities, MCP), speed-test system, OS info
pages, and the bulk of the v1.2.0 / v2.0.x feature surface are
intentionally absent — this fork was created by copying the plugin to a
second WP install and trimming back to a lighter baseline.

Archived for comparison and parallel-line testing. No further development
is planned on this line; the active line continues at v1.2.0 in
ranger/a-wp-notes.
