Pull request overview

This PR standardizes error handling across SeQuant by replacing uses of std::runtime_error / std::logic_error / std::invalid_argument / etc. with the project’s custom sequant::Exception, and updates unit tests and Doxygen @throw annotations accordingly.

Changes:

• Replaced standard-library exception types with sequant::Exception across core, MBPT domain, export, eval backends, and serialization code.
• Updated unit tests to assert Exception is thrown instead of STL exception types.
• Removed many now-unneeded <stdexcept> includes and added exception.hpp where required.

[Copilot]

Exception derives from std::exception, but SeQuant/core/utility/exception.hpp only includes <string>. Since this header no longer includes <stdexcept>, compilation can fail when std::exception is not available via transitive includes. Prefer adding #include <exception> to exception.hpp (or include <exception> here before including exception.hpp).

[Copilot]

SeQuant/core/utility/exception.hpp defines sequant::Exception : std::exception but does not include <exception>. This file includes exception.hpp directly (and no longer includes <stdexcept>), so it may fail to compile depending on include order. Prefer adding <exception> to exception.hpp (or include it here).
