fix: hashbang issue on Windows by upgrading pkgroll to 1.11+

[tlaukkanen]

pkgroll v1.9 had an issue as it was not adding the hashbang to generated .mjs file on Windows which caused the binary not to start with micro-agent when installed with npm install -g. pkgroll provided a fix for this in v1.11 as seen on privatenumber/pkgroll#40

The fix was applied here by installing latest v1.x release of pkgroll with npm install --save-dev pkgroll@1.11.1

cli.mjs before the fix with npm run build on Windows:

import { command, cli } from 'cleye';
import { dim, red, gray, green, blue, yellow } from 'kolorist';

...and with more recent pkgroll version as provided in this pull request:

#!/usr/bin/env node
import { command, cli } from 'cleye';
import { dim, red, gray, green, blue, yellow } from 'kolorist';
