## Summary

- Removes two incorrect checks in `RelativeReferenceValidator` that
rejected `#`, `?`, and `?#` as invalid relative references
- Moves these values to the valid test data provider and adds additional
valid cases (`#section`, `?query#fragment`)

Per [RFC 3986 Section
4.2](https://www.rfc-editor.org/rfc/rfc3986#section-4.2), these are
valid relative-references composed of `path-empty` + fragment and/or
query. The grammar allows zero-length paths, queries, and fragments.

This is a real-world issue: Drupal's
[Canvas](https://drupal.org/project/canvas) component builder and
[Byte](https://drupal.org/project/byte) theme use `format:
uri-reference` for link props in SDC (Single Directory Components), and
`href="#"` is common in HTML.

Fixes #909

…ption (#914)

## Description

Adds a CLI tool that runs one test case from the official JSON Schema
Test Suite by filename and human-readable description, making it faster
to debug spec compliance without running the full 6928-test suite.

## Summary

- `UriRetriever::retrieve()` now reads the root schema's `$schema`
keyword to determine whether to annotate with `id` (Draft-3/4) or `$id`
(Draft-6+)
- Schemas without a `$schema` keyword default to `$id`, matching the
library's Draft-6 default dialect
- Updated `testRetrieveSchemaFromPackage` to assert structure instead of
a brittle md5 hash

## Context

`UriRetriever::retrieve()` unconditionally stamped `$jsonSchema->id =
$resolvedUri` on every resolved schema. Draft-6 [renamed `id` to
`$id`](https://json-schema.org/draft-06/json-schema-release-notes#backwards-incompatible-changes),
but the annotation was never updated. This leaks a Draft-4 keyword into
schemas resolved under Draft-6/7, causing errors in strict validators
(e.g. Ajv: `NOT SUPPORTED: keyword "id", use "$id" for schema ID`).

The dialect is detected from the root schema *before* pointer
resolution, so sub-schemas inherit the correct keyword from their parent
document.

Internally safe — `SchemaStorage::findSchemaIdInObject()` already reads
both `id` and `$id`.

## Test plan

- [x] Full test suite passes (6928 tests, 0 failures)
- [x] Verified Draft-04 meta-schema → `id`, Draft-07 → `$id`, no
`$schema` → `$id`

…#915)

* fix: treat optional JSON Schema test suite cases as real tests (#913)

Previously, any optional test that threw an exception or produced the
wrong validation result was silently skipped via markTestSkipped, making
regressions in optional test coverage invisible in CI.

Remove the two dynamic markTestSkipped blocks so optional tests are
treated identically to required tests. The 76 currently-failing optional
tests are added explicitly to the $skip allowlist with comments
explaining why each group is not yet supported (bignum, float-overflow,
ecmascript-regex, cross-draft, idn-email, idn-hostname, iri,
iri-reference, regex format, relative-json-pointer).

* fix: Correct for +00:00 and zulu inputs

* refactor: Allow run-test-case without tes, running all test from group

* test: Skip more optional failling tests

* fix: Correct for zulu when used with PHP > 8.0
