feat(v7): regenerate presets-v7 for the corrected generator and update evidence

* content/presets-v7.* regenerated so the shipped 60 cards match the corrected
  generator (BPv4 range 566-29,754); Naming V3 names stay index-aligned with v6.
* package.json gains calibrate:v7-reference, audit:v7-solver-saturation,
  diagnose:v7-mechanism and explore:v7-mechanism; static-check audits the new
  scripts and artifacts; RELEASE-MANIFEST regenerated (341 files).
* docs/V7-DELIVERY-REPORT.md records convergence round 2: the verified fixes and
  their gates, the mechanism-ranking failure with evidence, the disproved
  ward/shield hypothesis, and the identified next lever (action cooldown/cost/
  priority are drawn randomly from one shared PRNG stream and move per-round
  throughput by up to ~6x; spec section 34 makes such numbers the solver's job).
