Add RoboCode CC:Ladder configs (rungs + base + per-model climbers)

rungs/robocode.yaml ranks the 115 human bots weakest->strongest from the Elo
round-robin (assets/robocode_elo). robocode.yaml is the base climber (sonnet-4-5)
and robocode__{gemini_3_5_flash,gpt_5_5,opus_4_7,opus_4_8,sonnet_5}.yaml are the
per-model variants (reference mini/models/llama_*.yaml, supplied at runtime with
LLAMA_API_KEY), mirroring the battlesnake/corewar/robotrumble ladder configs.
