Improvements & Fixes

The $.preferLocal option now also accepts a directory #886, #887.

$.preferLocal = true             // injects node_modules/.bin to the $PATH
$.preferLocal = '/foo/bar'       // attaches /foo/bar to the $PATH
$.preferLocal = ['/bar', '/baz'] // now the $PATH includes both /bar and /baz

Why not just $.env['PATH'] = 'extra:' + '$.env['PATH']?
Well, the API internally does the same, but also handles the win paths peculiarities.

Provided $.killSignal option for the symmetry with the $.timeoutSignal. You can override the default termination flow #885:

$.killSignal = 'SIGKILL'

const p = $({nothrow: true})`sleep 10000`
setTimeout(p.kill, 100)
  
(await p).signal // SIGKILL

$ opt presets became chainable #883:

const $$ = $({ nothrow: true })
assert.equal((await $$`exit 1`).exitCode, 1)

const $$$ = $$({ sync: true }) // Both {nothrow: true, sync: true} are applied
assert.equal($$$`exit 2`.exitCode, 2)

Enhanced the internal Duration parser #884:

const p = $({timeout: '1mss'})`sleep 999` // raises an error now

Abortion signal listeners are now removed after the process completes #881, #889, zurk#12, zurk#13.
Extended integration tests matrix, added nodejs-nightly builds and TS dev snapshots #888
