fix: fitness_flags not propagated to manifest entries for newly admitted candidates (#990)

Browse source 
Two changes in evolve.sh pool-admission code:

1. Include `fitness_flags` from evaluator JSONL in the manifest entry dict
   for newly admitted candidates (~line 866-874). Previously the field was
   omitted, so downstream `effective_fitness()` could never zero-rate a new
   candidate.

2. Use `effective_fitness(entry)` when appending new candidates to the
   evolved ranking list (~line 907), so ZERO_RATED_FLAGS defence applies
   at first admission — not only when re-ranking existing entries.
