* feat(benchmarks): prepare the benchmark refresh (pins, per-query journal, tokens, energy)

Adds what the overnight re-scoring campaign needs, without running any
scored benchmark and without changing retrieval or any score:

- LongMemEval-S cleaned release (98d7416c, sha256-pinned) as the opt-in
  --only longmemeval-cleaned leg, with a byte/record/key preflight; its
  artifact stem is never judged against the original file's floors.
- BEAM loads Mohammadta/BEAM at a pinned revision whose data equals the
  only data upload; every leg writes manifest.dataset, gathered into the
  run MANIFEST under datasets.
- Per-query journal beside --results-out (queries.jsonl, phases.jsonl) for
  LongMemEval, LoCoMo and BEAM, written after recall returns.
- Offline token counting (count_tokens, one pinned model) of retrieved
  texts and the bench-equivalent recall payload, plus full-history counts.
- Energy per scored query from the benchmark's own phase timeline under
  the existing sensor lifecycle; energy results may now be committed with
  their boundary stated.

* fix(bench): default count_tokens model id and legacy LME hash only when that leg ran

count_tokens defaulted to claude-opus-5, which the token-counting docs never
use; the default is now claude-opus-5-5, with its source. The run MANIFEST
wrote the original LongMemEval-S hash for a results dir that only scored the
cleaned file; the legacy field is now null unless longmemeval-s.json is there,
and the per-leg datasets map stays the source of truth.
