Bug: a stock clone of the repo has issues with the linter

Nobody has claimed this yet.

## Expected Behavior
I can commit all files after I scaffolded them

## Current Behavior
Right after generating the template, if I add and commit the files to the repo, the commit checks fail on a lint error that needs to be fixed:

```sh
✖ pnpm run lint:fix:
$ eslint . --fix /.changeset/config.json /.devcontainer/devcontainer.json /.prettierrc.json /eslint.config.js package.json tsconfig.json

.changeset/config.json
0:0 warning File ignored because no matching configuration was supplied

.devcontainer/devcontainer.json
0:0 warning File ignored because of a matching ignore pattern. Use "--no-ignore" to disable file ignore settings or use "--no-warn-ignored" to suppress this warning

.prettierrc.json
0:0 warning File ignored because no matching configuration was supplied

__tests__/app.test.ts
12:45 error 't' is defined but never used @typescript-eslint/no-unused-vars

package.json
0:0 warning File ignored because no matching configuration was supplied

tsconfig.json
0:0 warning File ignored because no matching configuration was supplied

✖ 6 problems (1 error, 5 warnings)

[ELIFECYCLE] Command failed with exit code 1.
husky - pre-commit script failed (code 1)

## Context

## Your Environment

- Library Version used:
- Node.js version (e.g. Node.js 5.4):
- Operating System and version (desktop or mobile):

Start by running pnpm run lint:fix and inspect __tests__/app.test.ts, eslint.config.js, and the listed JSON configuration files. Determine why the unused t error and ignored-file warnings occur, then verify that the generated template's commit checks complete without a lint failure.
