Support Semantic MediaWiki 7.0

[alistair3149]

Summary

Adds support for Semantic MediaWiki 7.0 and raises Semantic Meta Tags to 7.0.0-alpha. Following the convention for these extensions, the major version tracks the supported Semantic MediaWiki major directly (jumping from 4.x, skipping 5.x and 6.x).

Changes

Requirements & version

• extension.json: version → 7.0.0-alpha (requirements already declared MediaWiki >= 1.43 and Semantic MediaWiki >= 7.0.0).
• composer.json: branch-alias.dev-master → 7.0.0-dev.
• RELEASE-NOTES.md: new 7.0.0-alpha entry.

Source migration (Semantic MediaWiki 7.0 API)

• Migrate Semantic MediaWiki's deprecated data-item class aliases to their canonical 7.0 namespaces, in both production code and test mocks:
  • SMW\DIProperty → SMW\DataItems\Property
  • SMW\DIWikiPage → SMW\DataItems\WikiPage
  • SMWDIBlob → SMW\DataItems\Blob
  • SMWDIUri → SMW\DataItems\Uri
  • SMW\SemanticData → SMW\DataModel\SemanticData
• Replace the inline \OutputPage reference with the namespaced MediaWiki\Output\OutputPage.
• The two registered hooks (BeforePageDisplay, OutputPageParserOutput) are MediaWiki-core hooks and remain valid in MW 1.43+. The extension registers no Semantic MediaWiki hooks, so SMW 7.0's hook renames do not affect it.

CI & tooling

• main.yml: per-row MariaDB LTS spread (10.11 / 11.4 / 11.8 / 12.3) across MediaWiki 1.43–1.45 and PHP 8.1–8.4; bump actions/checkout and codecov/codecov-action to v6.
• codecov.yml: project + patch coverage status set to informational so coverage never gates CI.
• Add unit / integration composer scripts.
• Remove dead legacy CI: .scrutinizer.yml, tests/travis/, and the orphaned phpmd.xml.

Bug fix (separate commit)

• JsonLDSerializer referenced an undeclared self::$Logger in its EasyRdf catch branch, so any EasyRdf failure during JSON-LD generation raised an "undeclared static property" Error on a normal page view instead of degrading gracefully. The message is now routed through MediaWiki's LoggerFactory.

Security policy (separate commit)

• Add SECURITY.md documenting private vulnerability reporting. This is unrelated to the version bump, so it is kept as its own commit.

Verification

Run in the docker-compose-ci stack (MediaWiki 1.43 + Semantic MediaWiki dev-master + MariaDB 11.8):

• composer analyze — clean (lint + PHPCS + minus-x, exit 0, no warnings).
• composer phpunit — 80 tests, 160 assertions, OK (including the database-backed integration tests).
• Live smoke test on a real page view (index.php, not action=parse, since this extension injects content at page-display time): the property-derived <meta name="keywords"> / <meta name="description"> tags and the JSON-LD <script type="application/ld+json"> block all render correctly with no PHP errors.
