Many an `any`
summary
Implements several concrete std::any designs starting from a minimal version that stores the value on the heap via a void pointer plus a templated deleter and clone function, fixes forwarding-reference recursion with std::remove_cvref/decay, makes move operations noexcept using std::exchange, and adds an owned-object variant with virtual clone plus an embedded small-object buffer option. Explores allocator-aware (pmr) trade-offs and constexpr limits, attempts microbenchmarks but reports no reliable results yet.
