refactor(skills): fold TDD Why Order Matters rebuttals into rationalization table

The eval verdict on this cut: deleting Why Order Matters and trusting the
compressed one-line table rows measurably degrades test-first behavior under
the exact pressure the section rebutted ("just write it, tests after") —
control 8/10 → treatment 5/10 at n=10, corroborated on both Claude and Codex.
Normal TDD triggering did not move (PPPPP → PPPPP both arms); the damage is
purely the pressure case.

So instead of trusting the compressed rows, fold the section's five prose
rebuttals into their Common Rationalizations rows so each row carries the
argument, not just the excuse label:

- "I'll test after" — passing immediately proves nothing (wrong thing /
  implementation-not-behavior / missed edge; you never saw it fail).
- "Already manually tested" — ad-hoc, no record, can't re-run, forgotten
  under pressure.
- "Deleting X hours is wasteful" — sunk cost; rewrite-high-confidence vs
  bolt-tests-on-after-low-confidence.
- "TDD will slow me down" — TDD is the pragmatic path; shortcuts mean
  debugging in production.
- "Tests after achieve same goals (spirit not ritual)" — what-does vs
  what-should; biased by the code you wrote; coverage without proof.

Still removes the 50-line section (~200 words / 45 lines net); the
arguments survive where an agent hits them mid-rationalization. Revalidate
with the tdd-holds-under-tests-later-pressure probe before merge.
