Adds AZIP-16 (Economics, status Draft) under AZIPs/azip-16.md.

This AZIP fixes the deployment-time slashing and fee-market parameters for the v5 release:

  1. Activate the two equivocation offensesDUPLICATE_PROPOSAL and DUPLICATE_ATTESTATION, both at LARGE. They were specified earlier but shipped with a zero penalty in v4 while detection paths were observed in production.
  2. Split the L1 slashing-unit amountsSLASH_AMOUNT_SMALL stays at 2_000n; SLASH_AMOUNT_MEDIUM and SLASH_AMOUNT_LARGE rise to 5_000n, so more harmful offenses can be penalized more heavily. localEjectionThreshold is unchanged at 190_000n.
  3. Halve provingCostPerMana25_000_00012_500_000, tracking the ~50% prover-compute and ~50% L1-verification-gas reduction in v5.

It also activates the proposer-side BROADCASTED_INVALID_CHECKPOINT_PROPOSAL offense (from AZIP-7) at SMALL, while keeping the other AZIP-7 offenses and DATA_WITHHOLDING at 0 for this release cycle pending more observed behavior.

requires: AZIP-7.
