Pepijn dcd368e1f8 annotate: multi-call subtask quality chain (describe -> segment -> verify)
The single-call 'watch video -> emit subtask JSON' pattern makes the
VLM commit to structured output before reasoning about what it saw, so
it pattern-matches the task text and hallucinates steps. Split it into
an opt-in multi-call chain that grounds first and prunes last.

New PlanConfig flags (both default False -> single-call unchanged):
  * subtask_describe_first: a grounding pass narrates ONLY what is
    visible in the video (no subtask JSON yet). That description is
    injected into the segmentation prompt via a new {observation_block}
    placeholder, so the model segments its own grounded observations
    instead of the instruction text. +1 VLM call/episode.
  * subtask_verify: after segmentation, an adversarial pass re-watches
    the video and drops any candidate subtask it cannot see. Can only
    PRUNE (never add/rewrite/move) and fails open (keeps un-verified
    spans if the call returns nothing). +1 VLM call/episode.

Implementation:
  * _generate_subtasks now orchestrates describe -> segment -> verify.
  * Factored span cleaning into _clean_spans (shared by segment + verify
    outputs); added _describe_episode and _verify_subtasks helpers.
  * New prompts module_1_subtask_describe.txt (returns {description})
    and module_1_subtask_verify.txt (returns pruned {subtasks}).
  * module_1_subtasks.txt gains a {observation_block} slot at the top.

run_hf_job.py enables both for the RoboCasa run (3 VLM calls/episode
for subtasks). Combined with single-camera grounding + the embedded-
frame path, this is the high-quality configuration.

"""Launch ``lerobot-annotate`` on a Hugging Face job (vllm + Qwen3.6 MoE).
Spawns one ``h200x2`` job that:
1. installs this branch of ``lerobot`` plus the annotation extras,
2. boots two vllm servers (one per GPU) with Qwen3.6-35B-A3B-FP8,
3. runs the plan / interjections / vqa modules across the dataset
in free-form mode (each episode generates its own subtasks +
memory),
4. uploads the annotated dataset to ``--dest_repo_id`` (when set)
or back to ``--repo_id``.
Usage:
HF_TOKEN=hf_... uv run python examples/annotations/run_hf_job.py
Adjust ``CMD`` below to point at your own dataset / target hub repo.

# Phase 1 — plan module (subtasks + plan + memory).
# Embed decoded frames directly (use_video_url=false) rather than

# silently send NO video and the VLM would hallucinate subtasks from
# the task text alone. 2 fps gives dense visual grounding so the VLM
