The carrier (symptom/repro_known/recent_iter) and handoff
(red_test_path/cause_summary/constraint) field definitions were
tabled in full in both SKILL.md and debugger.md — the exact
duplication that let the `constraint` wording drift earlier.
Since the debugger agent runs in a fresh context, it must carry
both contracts inline regardless; that makes debugger.md the
natural single source. Mark its Carrier-contract and Output-format
tables authoritative, fold in the richer field descriptions that
only SKILL.md had, and reduce SKILL.md to naming the fields plus a
pointer — no field semantics restated. Drift-prone prose now lives
in exactly one place. Consistent with SKILL.md's own stated split
(debugger.md = source of truth; skill = trigger/dispatch/handoff).
