Fix: strip inline YAML comments when reading pnpm workspace globs (#570)

An inline comment on a pnpm-workspace.yaml packages line defeated the
end-anchored flow-list regex and the block-list state switch, so
workspaces outside apps/ or packages/ went unrecognized. Reuses the
engine's existing stripInlineYamlComment, matching context.mjs.
