refactor_changes

On rename, move, or delete of files or symbols, the extension should update the
idea index, import statements, embedded file references, comment references, and
other idea references that are affected.
The index should be resilient to duplication, particularly when ideas move between files:
the old hosting file URI must be cleared before or when the destination is reindexed.

Implemented by workspace-index.ts, index-service.ts, reqlan-idea-refactor.ts, and register-file-mutation-hooks.ts.
