FOLLOW-UP: Document breaking changes in changelog/migration guide (from PR #45)

[adnaan]

Context

This follow-up task was identified during the review of PR #45.

Source PR: #45
Suggested by: @claude[bot]

Task Description

The following breaking changes need to be documented in the changelog and/or migration guide:

1. Attribute renames (silent breaking changes):

   • lvt-no-intercept → lvt-nav:no-intercept (links)
   • lvt-no-intercept → lvt-form:no-intercept (forms)

2. Action field behavior change:

   • action form field is no longer reserved/excluded — it now flows through to ActionData
   • Routing now uses lvt-action hidden field (server) or lvt-form:action attribute (client)

3. Phase 1A attribute renames (from PR Phase 1A: Client attribute reduction — generic event router + removals #44):

   • lvt-click → lvt-on:click
   • lvt-submit → lvt-on:submit
   • lvt-debounce → lvt-mod:debounce
   • lvt-throttle → lvt-mod:throttle
   • Modal JS removed (use native <dialog>)

Original Comment

These are reasonable breaking changes, but the PR description should call them out explicitly, and if there's a changelog/migration guide it should be updated before merge.
