leftibot 88d3124272 Address review: fix all compiler warnings across GCC, Clang, and MSVC
Requested by @lefticus in PR #687 review.

Fix warnings-as-errors failures on all three compiler families:

- GCC Release: replace strncpy with memcpy in mystrdup (stringop-truncation)
- GCC ASAN+UBSAN Release: add bounds check in Operator() before indexing
  m_operators array — the recursive call could exceed the array size of 12,
  which is an actual out-of-bounds bug, not just a warning
- GCC: downgrade maybe-uninitialized to warning (false positive in libstdc++
  std::regex under sanitizers + optimizations)
- AppleClang: add default cases to all switch statements on Common_Types in
  boxed_number.hpp (Wswitch-default)
- AppleClang: mark Dispatch_Engine move ctor/assignment as deleted since
  shared_mutex is non-movable (Wdefaulted-function-deleted)
- AppleClang on macOS: suppress Wpoison-system-directories for /usr/local/include
- MSVC Release: suppress C4702 (unreachable code) around if-constexpr in
  proxy_functions_detail.hpp
- Fix unused variable warnings in emscripten_eval_test.cpp when asserts are
  disabled in Release mode
