v0.11.2

Changelog

Fixed

• A spec value YAML cannot build is a SpecParseError naming its line. An unquoted
  date the calendar does not have, such as 2026-13-01, a type tag over text it cannot
  read, such as !!int "" or !!bool maybe, or a \U escape past U+10FFFF raised a
  bare Python exception out of load_project and the CLI. The refusal now names the
  document and the line, and says to quote the value and drop any !! tag if it is
  meant as text. (#398)
