agentic-rsr: protocol 261107 round-0 roots

Run roots of the protocol-261107 (sim2sim, sim_init) evolve loop whose Round 0 was made off-cluster (alin19, 8x RTX 3090) and handed to Clariden, where the round-0 student is trained and the arms continue.

Layout: <task>/<root_name>/ is a run root exactly as the evolve loop expects it at /capstor/scratch/cscs/hongsu/imbw/261107_real2sim/runs/<root_name> (absolute paths already rewritten for Clariden by tools/root_relocate.py relocate):

• config.json - the frozen run config (digest = the Clariden config's), ledger.jsonl - every stage / LLM call;
• teacher_seed.json, teachers/ - the LLM-written starting teachers and the teacher set;
• r0/world.json - Sim R0 (the starting simulator: Truth + a uniform perturbation of every editable field);
• r0/teacher_rl/ - teacher adaptation in Sim R0 (CEM over the program parameters), r0/teacher_repair_r0/ - LLM program repairs of round 0;
• r0/round0/round0.json - round-0 summary (teacher before / after, demos, the student's training command), r0/round0/teachers/ - the teacher set after round 0, r0/round0/round0_demos.h5 - the round-0 demos (rendered observations + actions, the round-0 student's training data), r0/round0/demos_*/ - per-batch teacher logs.

The policy-only arm of the same seed (*_policyonly_s<k>) shares round 0 with the ours arm (*_ours_s<k>): same Sim R0, teacher set, demos and round-0 student. <task>/_manifests/<root_name>.json lists every file with its size and sha256 (checked after download by tools/clariden/hf_fetch_root.sh). Code: branch 261107/real2sim of prj-agentic-rsr (tools: branch 261107/local-round0).
