v0.11.0

• Changed. Accepts rasuvaeff/property-testing-core ^0.7, ^0.8 and
  ^0.9 alongside ^0.5 and ^0.6, and develops against
  rasuvaeff/property-testing-testo ^0.9. None of the engine's breaks on
  that stretch reach this package: it passes no generator into
  Gen::oneOf()/Gen::elements() (0.9), no delimited pattern into
  Gen::regex()/Gen::stringMatching() (0.9), builds no CounterExample
  argument that 0.10 renames, and reads none of the counters 0.8–0.9
  redefined. The suite is green against every line it declares.

• Changed. Accepts rasuvaeff/openapi-contract ^0.10 alongside ^0.8
  and ^0.9. 0.10 bounds what a document expands into (Limits::$documentNodes,
  which the generator never builds documents large enough to reach) and finds
  operations through a route index instead of a scan; neither changes how a
  document compiles or how a message is judged, and this suite is green against
  every line it declares.

• Changed. Accepts rasuvaeff/openapi-contract ^0.9 alongside ^0.8.
  0.9 narrows the contract's public surface — Operation::__construct() is
  @internal and the byte budgets moved from Contract::MAX_* constants to a
  Limits object — without changing how documents compile or how messages are
  judged, so this suite passes against both lines and both stay supported.

• Changed. Requires rasuvaeff/openapi-contract ^0.8. That release
  refuses documents 0.7 accepted — an unreadable subschema, a parameter
  declared twice, a boolean written as a string — and reads several things
  differently: $ref siblings by dialect, a content map by specificity, a
  trailing slash as part of the path, a repeated parameter as a violation. The
  generator builds documents this package controls, so nothing here changed
  with it; the constraint moves so that --prefer-lowest exercises the
  compiler this suite is written against.

• Internal. Two tests built documents rasuvaeff/openapi-contract no
  longer accepts, so this suite went red against its development branch while
  staying green against the release. The shared multipart fixture is a document
  that compiles again, and the malformed header declarations it carried — a
  value that is not an object, a name that is not a string — moved to a test
  that hands the generator an Operation built by hand, which is the only way
  such a shape can still reach it. rejectsAPartContentTypeMismatchItCannotConstruct
  builds its operation the same way, so every dataset reaches the refusal it
  is named for.

• Internal. A Contract dev-master job runs this suite against the
  contract's development branch on every relevant pull request. It does not
  gate the build — that master may legitimately be ahead of what this package
  supports — but the day it goes red is the day to look, instead of finding out
  at release time.
