fix(droid-control): repair YAML frontmatter of command files

The argument-hint field in demo.md, qa-test.md and verify.md was a bare
value containing multiple double-quoted tokens joined by 'or', which
terminates the first flow scalar and causes strict YAML parsers to fail.
Wrap each value in single quotes so the whole hint is one valid scalar
while preserving the human-readable double-quoted placeholders.
