fix(cli): use dynamic import for @inquirer/prompts in config command (#392)

* fix(cli): use dynamic import for @inquirer/prompts in config command

The config command (added in #382) reintroduced the pre-commit hook hang
issue that was fixed in #380. The static import of @inquirer/prompts at
module load time causes stdin event listeners to be registered even when
running non-interactive commands, preventing clean process exit when
stdin is piped (as pre-commit does).

Convert the static import to a dynamic import that only loads inquirer
when the `config reset` command is actually used interactively.

Fixes #367

* chore: add ESLint with no-restricted-imports rule for @InQuirer

Add ESLint configuration that prevents static imports of @inquirer/*
modules. This prevents future regressions of the pre-commit hook hang
issue fixed in this PR.

The rule shows a helpful error message pointing to issue #367 for context.
init.ts is exempted since it's already dynamically imported from the CLI.

* ci: add ESLint step to lint job

Run `pnpm lint` in CI to enforce the no-restricted-imports rule
that prevents static @InQuirer imports.
