Add separate bytecode instructions for environment lookups that must stay dynamic, such as eval- and with-sensitive scopes. Keep the coordinate variants for eagerly resolved declarative environments so their operands can be treated as immutable at runtime. This removes cached-coordinate mutation from the interpreter paths and updates the bytecode expectations for the new dynamic lookup opcodes.
