twaco v0.1.44

Added

• twaco check has an offline, advisory structure gate. Set [gates] structure_xsd (or
  TWACO_STRUCTURE_XSD) to an XSD, Eclipse plugin JAR, or directory; the vendor schema is read
  only at runtime and is never stored by twaco. It reports unknown attributes, unexpected or
  missing children, text where only elements belong and values of the wrong type (a boolean that
  is not true/false). Child order, aspect.* attributes, server-computed sections, an empty
  ExtensionPackages, the empty Subscriptions a 10.2 export writes under a Thing, and
  collections the schema does not know are not findings.

Notes

• A fields.json written before 0.1.43 lists fields as its XML did. It still reads as in sync;
  the next extract of that DataShape rewrites it once, in ordinal order.

Fixed

• twaco sync leaves an unedited service script whose lines all end \r\r\n (a CRLF export
  checked out with CRLF conversion) alone again. Since 0.1.40 it counted those endings as mixed
  and rewrote the payload, so every sync reported the script as changed.
