Spec cross-check vs the 1995 manual: reads CORRECT, numbers are 4.0-vs-4.10 drift

Audited our live streamed subsystem config against the manual's per-mech
stat sheets (new BT_SPEC_LOG dump: torso speed/limits, heat-sink count,
reservoir capacity, at subsystem ctor).

RESULT: structure + semantics align perfectly; the tuning NUMBERS
differ -- because the manual is Tesla 4.0 and our content is release
4.10.  Point-release balance drift, NOT a reconstruction bug:
- Owens + Blackhawk are the two fixed-torso mechs in BOTH (speed 0,
  limit ~0, torsoHorizontalEnabled=0); the other four twist-enabled --
  our reads correctly identify every case
- torso speed/limit + heat-sink count exist per-mech exactly as the
  manual documents; only the values were retuned 4.0->4.10 (e.g. torso
  speed MadCat 80->50, heat sinks Loki 38->15)
- reservoir coolantCapacity reads a flat 20 = the coolant THERMAL
  capacity (game units), NOT the manual's per-mech 'liters' (a
  display/flavor quantity with no single subsystem field) -- different
  measures, not a bug

CONCLUSION: do NOT retune content to the manual -- BTL4.RES is the
authentic 4.10 shipping data; the 4.0 manual's numbers are an earlier
pass.  The manual CONFIRMS our structural fidelity.

BT_SPEC_LOG retained for re-auditing.  Follow-up (structural, less
drift-prone): the per-mech coolant-loop weapon/generator assignments.
