8cc75d444e fix box mode: reset bounds before each objective 
update_lower_lex updates m_lower for subsequent objectives with saved
values from the current model. Reset m_lower[i] and m_upper[i] to
their initial values before optimizing each objective so earlier
objectives do not contaminate later ones.

fbbb582650 fix test: copy Z3_ast_to_string results before next call 
Z3_ast_to_string returns a pointer to an internal buffer that is
overwritten on the next call. Store results in std::string immediately
to avoid reading a stale, garbled buffer.

1c70b9e6ee fix box mode: isolate m_lower/m_upper between objectives 
geometric_lex's update_lower_lex updates m_lower for all subsequent
objectives with saved values from the current model. In box mode this
contaminates later objectives' starting bounds, causing platform-dependent
results. Save and restore m_lower/m_upper across iterations so each
objective starts from a clean state.

acd2e9475d fix #9030: box mode objectives are now optimized independently 
In box mode (opt.priority=box), each objective should be optimized
independently. Previously, box() called geometric_opt() which optimizes
all objectives together using a shared disjunction of bounds. This caused
adding/removing an objective to change the optimal values of other
objectives.

Fix: Rewrite box() to optimize each objective in its own push/pop scope
using geometric_lex, ensuring complete isolation between objectives.
