0.12.0

The design decisions of the 0.10 audit (docs/plans/audit-0.10.md §6 in the specification workspace). Three change
signatures; this is the one breaking minor that carries them, so that the next adapter is written against the final ones.

Changed

• Attribute\Param\FieldCondition no longer extends Condition, and Equals::evaluate() is gone. A field condition
  is read by the graph's ParamExtractor (heldFor() of the value it reads for field()), so it never reads the object
  itself; evaluate() built a plain ParamExtractor inside and answered wrong on Eloquent attributes. when accepts
  string|Condition|FieldCondition|Closure. To evaluate one by hand: $extractor->condition($subject, $equals). A custom
  FieldCondition drops its evaluate() (an extra method is harmless); a custom Condition is unchanged.
• The extractor is a required parameter: Url\AttributeUrlResolver::__construct($reader, $extractor, ...) and
  ::fromConfig($config, $reader, $extractor, ...), Url\ObjectChangeHandler::__construct($rules, $resolver, $extractor, $logger), Attribute\ChangeClassifier::classify($rule, $subject, $extractor, $changedFields, $changeSet),
  Attribute\UrlRule::appliesTo($subject, $extractor). Each fell back to new ParamExtractor() when the argument was
  omitted, and the only symptom of an adapter forgetting it was URLs lost on Eloquent/ActiveRecord objects; now static
  analysis catches it. ParamExtractor::plain() names the DSL-only extractor for graphs built by hand (plain PHP,
  Doctrine). IndexNowKit::create(extractor:) and the facade constructor stay optional: the facade derives it from the
  resolver (Url\ParamExtractorAwareInterface).
• IndexNowKit::create() and the constructor without resolver: build AttributeUrlResolver::fromConfig(), as
  Adapter\ServicesBuilder does, instead of NullUrlResolver: a class with #[IndexNow] handed to the bare facade resolves
  its url/urls rules (a route: rule without a router is an error the guard logs), where before it silently yielded
  nothing. resolver: new NullUrlResolver() is the explicit way to resolve nothing.

Added

• IndexNowKit::submitEntities(), the bulk twin of submitEntity() (the submitX/submitXs scheme of every adapter:
  submitModels(), submitRecords()). submitAll() is its @deprecated alias, removed in the next minor
  (ClientInterface::submitAll(), the URL-level method, is unrelated and stays).
• Attribute\ParamExtractor::plain().

Documentation

• docs/bc.md: ObjectChangeHandler::renamed($subject, $changeSet, $previous, $selfFields) — $previous is the contract
  for adapters whose objects cannot be reset by reflection (Eloquent); Attribute\SubjectReaderInterface stays read-only,
  no write() is planned. docs/attribute-reference.md: conditions rewritten for the split.
