Language: parent:: and static:: resolution in extends chain (#1858) - #1883
Merged

Conversation
VM/JIT resolve parent::method() to the parent vtable with implicit $this for instance methods; static:: uses called-class LSB. Compiler rejects parent::class at compile time; VM rejects parent::class at runtime. Add compliance PHPTs and sync capability docs. Bump spine canonical count to 585 (BootstrapSelfhostBundleTest + roadmap footnotes). Co-authored-by: Cursor <cursoragent@cursor.com>
