89a2734bff fix: address review findings for diverse seed population (#638)
- evolve.sh: fix fail-in-subshell bug — run seed-gen-cli as a direct
  command so its exit code is checked by the parent shell and fail()
  aborts the script correctly; redirect stderr to log file instead of
  discarding it with 2>/dev/null
- seed-generator.ts: reorder enumerateVariants() to put
  STAKED_THRESHOLDS outermost (192 entries/block) so that
  selectVariants(6) with stride=192 covers all 6 staked% thresholds;
  remove false doc claim about "first variant is current seed config";
  add comments explaining CI=0n is intentional in all presets
- seed-gen-cli.ts: emit a stderr diagnostic when count exceeds the
  1152-variant cap so the cap is visible rather than silently producing
  fewer files than requested
- test: strengthen n=6 test to assert all STAKED_THRESHOLDS values are
  represented in the selected variants

850131b74f fix: feat: Push3 evolution — diverse seed population (#638)
Add seed-generator.ts module and seed-gen-cli.ts CLI that produce
parametric Push3 variants for initial population seeding.

Variants systematically cover:
  - Staked% thresholds: 80, 85, 88, 91, 94, 97
  - Penalty thresholds: 30, 50, 70, 100
  - Bull params: 4 presets (aggressive → mild)
  - Bear params: 4 presets (standard → very mild)
  - Tax distributions: exponential (seed), linear, sqrt

Total combination space: 6×4×4×4×3 = 1152 variants.
selectVariants(n) samples evenly so every axis is represented.

evolve.sh gains --diverse-seeds flag: when set, gen_0 is seeded with
parametric variants instead of N copies of the same mutated seed.
Remaining slots (if population > generated variants) fall back to
mutations of the base seed.

All generated programs pass transpiler stack validation (33 new tests).
