add title and abstract to .entry.json and index.html files

We add an initial "_title_" and "_abstract_" to all entry `.entry.json` files.

The `bin/csv2entry.sh` tool reads the `summary.csv` file and
loads the "_title_" and "_abstract_" to entry `.entry.json` files.

to "1.4 2024-09-27".

The `bin/cvt-submission.sh` tool adds "_title_" and "_abstract_" to the
.entry.json based on the `.info.json` file.

`<h3>abstract</h3>` header.
