Fix: Memory leak in autocomplete fieldset

[TomA-R]

Summary

Fixes memory leak in hosted autocomplete fieldset component.

Issue

The 'change' event listener added during input creation was never removed
during detach, causing the listener to persist and accumulate in memory.

Changes

• Remove 'change' event listener in detach() method

Testing

• Build passes with NX
• No breaking changes to API

Note

High Risk
Touches postMessage-based checkout extension communication, origin checks, and iframe resize behavior in a large generated bundle that is hard to review.

Overview
Rebuilds dist/cjs/extension.js for the checkout extension client. The generated bundle swaps in a newer iframe-resizer (child/parent) and lodash, and exposes a renamed public API (initializeExtensionService, ExtensionCommandType / ExtensionEventType).

Host–iframe messaging is reworked: command/event names move to EXTENSION:* (reload checkout, loading indicator, iframe style, shipping re-render, consignments). Resize setup now uses parentIFrame (autoResize, taggedElement / bodyOffset, data-iframe-height). Origin parsing, error types, and load-timeout copy also change.

This is a compiled artifact; source-level intent is not visible in the diff. Reviewers should treat it as a vendor/SDK bump rather than a small leak fix.

Wrong bundle updated for fix

High Severity

This commit only rebuilds extension.js, which does not contain HostedAutocompleteFieldset. The PR claims to fix the autocomplete change listener leak in detach(), but that logic lives in the hosted-form bundles. Those artifacts are unchanged, so the memory leak remains in production while an unrelated extension rebuild is shipped.
