fix(template): streamline Copier configuration and enhance mise setup

Refactor `copier.yaml` by removing outdated file migrations and adjusting `_skip_if_exists` rules, simplifying template maintenance.
Introduce a `mise` enter hook in `10-python.toml` to automatically run `mise run install` for improved developer environment setup.
Remove `playground/` from `.gitignore` to allow tracking of this directory.
