fix: ensure woke.customArgs are passed to woke CLI

[LarytheLord]

Summary

Fix woke.customArgs not being applied when spawning the woke CLI.

Root cause

In runWoke(), args.concat(this.settings.customArgs) was called without assigning the result, and args was then overwritten by buffer/file args.

Fix

• Start args from this.settings.customArgs.
• Append the standard extension args (--stdin -o json or -o json <file>).
• Keep existing behavior for stdin/file mode unchanged.

Docs

• Clarify woke.customArgs in README with a concrete CLI-argument example.

Validation

• npm run lint (warnings only; no errors)
• NODE_OPTIONS=--openssl-legacy-provider npm run compile

Closes #22.
