…tion alignment

- Add BoolOp constant folding with short-circuit semantics in compile_expression
- Add constant truthiness evaluation for assert statement optimization
- Disable const collection/boolop folding in starred unpack and assignment contexts
- Move annotation block generation after body with AnnotationsPlaceholder splicing
- Reorder insert_superinstructions to run before push_cold_blocks (matching flowgraph.c)
- Lower LOAD_CLOSURE after superinstructions to avoid false LOAD_FAST_LOAD_FAST
- Add ToBool before PopJumpIf in comparisons and chained compare cleanup blocks
- Unify annotation dict building to always use incremental BuildMap + StoreSubscr
- Add TrueDivide constant folding for integer operands
- Fold constant sets to Frozenset (not Tuple) in try_fold_constant_collection
- Add PyVmBag for frozenset constant materialization in code objects
- Add remove_redundant_const_pop_top_pairs pass and peephole const+branch folding
- Emit Nop for skipped constant expressions and constant-true asserts
- Preserve comprehension local ordering by source-order bound name collection
- Simplify annotation scanning in symboltable (remove simple-name gate)
