feat: promote 3 ccb_fix variance runs to official (leakage-cleaned)

Promote ccb_fix_haiku_20260228_185835 (R1, 25 tasks),
ccb_fix_haiku_20260228_205741 (R2, 25 tasks), and
ccb_fix_haiku_20260228_230722 (R3, 20 tasks) to official.

3-run variance on 20 common tasks:
  BL  mean: 0.510 +/- 0.012
  MCP mean: 0.599 +/- 0.016
  Delta:   +0.089 +/- 0.006

Instruction files were cleaned of answer leakage (e2304ed)
before all 3 runs.
