feat: connect resource replacement to the editor lifecycle

Depends on PR: feat: support resource replacement in CodeMirror

Expose resource replacement configuration and operation controls through the editor
API. Lazily share configured dependencies across both modes, prevent mode switching
while processing, and release views/controllers safely on detach and StrictMode
reconnection. Add integration documentation and editor integration coverage.

Summary by Sourcery

Connect asynchronous resource replacement to the editor lifecycle and expose the controls needed to manage it safely.

New Features:

• Expose resource replacement configuration, status events, pending-operation queries, and cancellation controls through the public editor API.
• Support asynchronous resource replacement for configured paste and drop content in both WYSIWYG and markup modes.

Bug Fixes:

• Safely cancel pending replacements and ignore late responses when editors detach, reconnect under StrictMode, or are destroyed.
• Prevent mode switching and local history actions while resource replacement operations are pending.

Enhancements:

• Share lazily created editor dependencies and resource replacement controllers across both editing modes while preserving editor content across lifecycle reconnections.

Documentation:

• Add comprehensive documentation for configuring resource metadata, resolver behavior, lifecycle integration, history, and standalone CodeMirror usage.

Tests:

• Add editor lifecycle unit coverage and cross-browser integration coverage for resource replacement, cancellation, mode locking, history, serialization, focus, and native clipboard behavior.
