package:cognitive_complexity v0.2.2+2

• Refine the skill's 3-Tier Decomposition Rubric per empirical feedback
  (#19):
  • "Slice at natural seams" rule: enlarge slices to whole loops/state
    machines before classifying; solves coupled 2-variable state
    (queue + visited) without weakening the Tier 3 gate (stays at >= 3
    with recorded evidence).
  • Named records for private/file-local slices at any output count;
    dedicated Result dataclasses reserved for public API boundaries
    (aligns the rubric with the data_flow signature synthesizer).
  • Pattern E: loop-body extraction with explicit signal returns
    (enum/sealed) instead of boolean control-flow flags; ordered
    dispositions for control-flow escapes.
  • Domain-modeling exit: promoting coupled state to a real named, tested
    domain class is out of rubric scope — the gate bans _Runner facades,
    not real abstractions.
• No library or CLI code changes.
