Adjust gridtk list output to fit terminal width

Fixes #13

Adjust the `gridtk list` output to fit terminal width and add a `--full-output` option.

* **src/gridtk/cli.py**
  - Update the `list_jobs` function to adjust column widths based on terminal size.
  - Add logic to truncate long content with ellipses in the `list_jobs` function.
  - Add a new option `--full-output` to the `list_jobs` command to view the full output without truncation.

* **tests/test_gridtk.py**
  - Add unit tests to verify the new behavior of the `gridtk list` command.
  - Add unit tests to verify the `--full-output` option for the `gridtk list` command.

* **README.md**
  - Update the documentation to reflect the new behavior of the `gridtk list` command.
  - Add information about the `--full-output` option for the `gridtk list` command.

* **.devcontainer.json**
  - Add a devcontainer configuration file with tasks for testing, building, and launching the project.

+### Adjusting `gridtk list` Output to Fit Terminal Width
+
+By default, the `gridtk list` output now adjusts to fit the terminal width, with truncation or ellipses for long content. This ensures that the output remains readable and does not span multiple lines. If you wish to view the full output without truncation, you can use the `--full-output` option:
+
+```bash
+$ gridtk list --full-output
+  job-id    grid-id  nodes    state        job-name    output                  dependencies    command
+--------  ---------  -------  -----------  ----------  ----------------------  --------------  --------------------
+       1     136132  None     PENDING (0)  gridtk      logs/gridtk.136132.out                  gridtk submit job.sh
+```
+
+This enhancement improves readability and allows you to quickly parse job-related information without resizing your terminal or handling multiline outputs for each job.
