fix(story-mode): name the files, say when a repository is new, and when a push stayed on this computer

From review round 9 (a newcomer to the project):
- One or two files are named, not counted: "Claude writes .gitignore and
  saves the work", "Claude changes rename_by_date.sh.", "Claude writes
  the new files mathx.py and test_mathx.py." Three or more are counted.
- The first save in a folder Claude turned into a repository says so:
  "Claude starts a git repository and saves the work: …". A `git init
  --bare` (the push target) does not count, nor a folder that already
  had commits.
- A push to a repository in a folder on this computer (`To ./origin.git`)
  is a copy, not an upload: "then copies it to origin.git, a folder on
  this computer", and the final chip reads "copied to origin.git".
- A tool lookup for plan mode reads "Claude gets ready to plan."
