pub const DEBUG_FLAG_PROLOGUE_END: u8 = 0b0000_0010;Expand description
flags bit 1: this entry’s own bytecode_offset is the prologue-end
landing point for a breakpoint set on the enclosing container
(docs/debugger-spec.md §2.4) — past any leading parameter-binding
DeclareTemps / choice-output prologue bytes. At most one entry per
container carries this bit.
