0.126 → 0.127 — an acroform quill's field spec is Form.yaml, and a field box that shows nothing fails to open

An acroform quill's field spec is Form.yaml, capitalized as Quill.yaml is. A quill holding form.yaml fails to open as acroform::legacy_form_yaml, and so does one holding both. Rename the file to Form.yaml; its contents are valid as they are. No acroform quill opens on both 0.126 and 0.127: 0.126 reports a Form.yaml quill as acroform::missing_form_spec. Declare requires: ">=0.127" in Quill.yaml so an older Quillmark release names the one it needs. On a case-insensitive file system, rename with git mv form.yaml Form.yaml: a plain mv changes the name on disk but not in git, so a clone elsewhere still holds form.yaml.

An acroform quill whose Form.yaml gives a field a rect with no width or height, or one wholly off its page, fails to open as acroform::invalid_field_rect, where it opened and rendered with that field's value nowhere to be seen. The error names the field and its rect. A box that only crosses its page's edge still loads. Give the box a positive w and h on its page, or drop the field from Form.yaml.
