v0.7.1

Changed

• Modified files can now carry forward prior AI evidence when their committed
  content matches an earlier unlinked workspace observation created by
  semantica checkpoint. Evidence is limited to that observation's event window
  and does not replace current-window line attribution. Missing or mismatched
  observations fail closed.
• Reduced post-tool hook latency by reusing the already-resolved HEAD.
• Reduced post-tool cleanup latency by deleting closed snapshot refs in one
  conditional git update-ref transaction.

Fixed

• Cursor shell tool windows now use the command's working directory, so
  cross-repository changes and their turn bundles are recorded in the
  repository where they occur.
  Missing or invalid routing state is not redirected to the session repository.
