Fix deploy silent no-op after zx 7→8 upgrade

[Copilot]

The v1.0.25 build upgraded zx from v7 to v8, which introduced two breaking behavioral changes that caused deploys to silently succeed without running any tasks.

verbose default flipped to false

zx 8 defaults verbose to false (was true). All command output—stdout and stderr—is captured internally but never printed to the Actions log.

Fix: Set $.verbose = true after import.

quote("") now emits an explicit empty shell argument

zx 7's quote("") returned "" (vanishes in shell). zx 8 returns $'' (explicit empty positional arg). When the optional recipe input is unset, the command becomes:

php vendor/bin/dep deploy stage=uat $'' --no-interaction --ansi -v

That spurious empty argument causes Deployer (v8 especially) to silently no-op.

Fix: Use arrays instead of strings for optional args (recipe, verbosity). Empty arrays produce no arguments in zx template literals:

const recipeArgs: string[] = []
if (recipeInput !== '') {
  recipeArgs.push(`--file=${recipeInput}`)
}
await $`${phpBin} ${bin} ${cmd} ${recipeArgs} --no-interaction ${ansi} ${verbosityArgs} ${options}`
