🎯 What: The lower_instruction method in compiler/bytecode/src/lowering.rs contained a massive match statement covering all IR operations, leading to poor readability. This PR refactors it by extracting logical families of instructions into private helper methods (lower_memory_op, lower_arithmetic_op, lower_call_op, lower_access_op, lower_collection_op, lower_exception_op).

💡 Why: Breaking down this monolithic function drastically improves the readability and maintainability of the bytecode lowering pipeline, making future modifications easier to navigate.

Verification:

  • Ran cargo check -p techscript_bytecode to verify syntax and logic preservation.
  • Ran cargo test -p techscript_bytecode to confirm zero regressions in instruction lowering and bytecode emission tests.
  • Code review performed to ensure behavioral equivalence.

Result: A much cleaner, structural improvement to the core compiler lowering module.

…d helper methods

Extracts the large `match` statement in `BytecodeLowerer::lower_instruction` into discrete private helper methods based on instruction families (memory, arithmetic, calls, access, collections, exceptions). This structurally simplifies the main router function without altering behavioral logic.
