New features:

• Add class, interface, and trait hierarchy tables to PhoundPlugin's SQLite database (#5443, #5460)
• Add function/method signatures and parameter tables to PhoundPlugin's SQLite database (#5458)

• Fixed false PhanTypePossiblyInvalidDimOffset warnings when accessing keys on mixed-typed variables with inferred array shapes (#5444)
• Fixed false PhanTypePossiblyInvalidDimOffset when array<string,mixed> or array<int,mixed> is in the union type (#5455)
• Fixed get_class() return type to erase template parameters from class-string<> (#5454)
• Fixed false PhanUnreferencedUseNormal when class references (A::class, A::CONST) appear in large arrays subject to literal array summarization (#5462)
• Fixed nullsafe method call type inference losing nullability when it comes from PHPDoc annotations (#5463)
• Fixed Xdebug restart handler for PHP 8.4+ where proc_open no longer passes file descriptors (#5464)

Miscellaneous:
