BREAKING CHANGES

• the LightningFS/IndexedDB VFS backend and its
  boot-time IDB→OPFS migration are removed. OPFS is the only filesystem
  backend; profiles that never ran a migration-capable build cannot carry
  legacy 'slicc-fs' content forward. The slicc-fs-cleanup command remains
  solely to delete the leftover IndexedDB database, and the
  @isomorphic-git/lightning-fs dependency is gone.

• the legacy Layout/ChatPanel UI is gone. The
  @slicc/webcomponents shell is the UI for every float — standalone,
  electron-overlay, hosted-leader, cherry, extension side panel, and the
  detached popout. The ?ui=wc opt-in flag no longer exists (the WC shell
  always boots), the legacy chat/layout stylesheets survive only as the
  scoped dialog subset in legacy-styles.ts, and any integration that
  reached into legacy DOM (.chat-panel, Layout globals) must move to the
  slicc-* component contracts.
