* fix: address issues 1,2,4,5 and add Goal API to Go bindings
Issue 2 (Go): Add Substitute, SubstituteVars, SubstituteFuns to Expr
Issue 4 (Go): Add GetDecl, NumArgs, Arg to Expr for AST app introspection
Goal API (Go): Add IsInconsistent and ToDimacsString to Goal
ASTVector (Go): Add public Size, Get, String methods
ASTMap (Go): Add ASTMap type with full CRUD API in spacer.go
Issue 1 (Go): Add Spacer fixedpoint methods QueryFromLvl, GetGroundSatAnswer,
GetRulesAlongTrace, GetRuleNamesAlongTrace, AddInvariant, GetReachable
Issue 1 (Go): Add context-level QE functions ModelExtrapolate, QeLite,
QeModelProject, QeModelProjectSkolem, QeModelProjectWithWitness
Issue 5 (OCaml): Add substitute_funs to z3.ml and z3.mli

* fix: add substitute_funs to Expr module sig in z3.ml
The internal sig...end block in z3.ml (the module type declaration for Expr)
was missing val substitute_funs, causing OCaml compiler error:
The value substitute_funs is required but not provided

New methods:
- Expr.getNumeralDouble(): retrieve any numeral as a double
- IntNum.getUint(): extract numeral as unsigned 32-bit value
- IntNum.getUint64(): extract numeral as unsigned 64-bit value
- RatNum.getSmall(): numerator/denominator as int64 pair
- RatNum.getRationalInt64(): numerator/denominator (returns null on overflow)
Each is a thin wrapper around the existing Native binding.
Added examples to JavaExample.java covering all new methods.
* add Expr.isGround() to Java API
Expose Z3_is_ground as a public method on Expr. Returns true when the
expression contains no free variables.
* add Expr.isLambda() to Java API
Expose Z3_is_lambda as a public method on Expr. Returns true when the
expression is a lambda quantifier.
* add AST.getDepth() to Java API
Expose Z3_get_depth as a public method on AST. Returns the maximum
number of nodes on any path from root to leaf.
* add ArraySort.getArity() to Java API
Expose Z3_get_array_arity as a public method on ArraySort. Returns
the number of dimensions of a multi-dimensional array sort.
* add DatatypeSort.isRecursive() to Java API
Expose Z3_is_recursive_datatype_sort as a public method on
DatatypeSort. Returns true when the datatype refers to itself.
* add FPExpr.isNumeral() to Java API
Expose Z3_fpa_is_numeral as a public method on FPExpr. Returns true
when the expression is a concrete floating-point value.
* add isGroundExample test to JavaExample
Test Expr.isGround() on constants, variables, and compound
expressions.
* add astDepthExample test to JavaExample
Test AST.getDepth() on leaf nodes and nested expressions to verify
the depth computation.
* add arrayArityExample test to JavaExample
Test ArraySort.getArity() on single-domain and multi-domain array
sorts.
* add recursiveDatatypeExample test to JavaExample
Test DatatypeSort.isRecursive() on a recursive list datatype and a
non-recursive pair datatype.
* add fpNumeralExample test to JavaExample
Test FPExpr.isNumeral() on a floating point constant and a symbolic
variable.
* add isLambdaExample test to JavaExample
Test Expr.isLambda() on a lambda expression and a plain variable.
- api_fpa.cpp: add RETURN_Z3(nullptr) after SET_ERROR_CODE in Z3_mk_fpa_sort to prevent fall-through to mk_float_sort with invalid params
- api_seq.cpp: add null check for str in Z3_mk_string; add null check for str when sz>0 in Z3_mk_lstring; add lo<=hi validation in Z3_mk_re_loop
- api_array.cpp: add explicit n==0 validation in Z3_mk_array_sort_n
- api_solver.cpp: rename local variable 'c' to avoid shadowing Z3_context param in Z3_solver_propagate_created/decide/on_binding; move init_solver call inside file-exists branches of Z3_solver_from_file
- api_ast.cpp: add null check for target in Z3_translate; add null check for _from/_to arrays when num_exprs>0 in Z3_substitute
- api_model.cpp: add CHECK_NON_NULL(m) in Z3_add_func_interp; add CHECK_NON_NULL(a) in Z3_model_get_const_interp; add null check for target in Z3_model_translate
- api_opt.cpp: add null check for weight string in Z3_optimize_assert_soft
- api_quant.cpp: add num_patterns==0 validation in Z3_mk_pattern
