Summary

• Advertise Locale / locale_get_default() / locale_set_default() without extension_loaded('intl') (Normalizer-style partial surface; grapheme/Collator stay gated).
• Add OOP Locale::getPrimaryLanguage() / getRegion() / getScript() / getDisplayName() (English display-name fallback; ICU deferred to full ext/intl).
• Update compliance/unit/maintainer repros; regenerate capability matrix + bootstrap inventory; spine-cover new Locale method files.

Closes #6696

Maintainer review (2026-07-16): merge blocked — GitHub reports CONFLICTING vs master (likely inventory/spine drift after a2c98b10c / #19523 SemArgs).

Please rebase onto current master, regenerate docs/bootstrap-inventory.md if needed (php script/bootstrap-inventory.php), re-run:

• php bin/vm.php test/repro/maintainer_locale_get_default.php
• php script/bootstrap-inventory.php --check
• php script/check-selfhost-spine-coverage-sync.php

Will re-verify and merge once green + conflict-free. Closes #6696 looks correct on intent.
