Erik 0cb97aa594 UN-2 RESOLVED: GetMaxSpeed x4 is byte-verified retail; doc-comment was the misread 
The register's UN-2 row recorded a contradiction: the GetMaxSpeed XML doc
claimed the bare run rate was retail-correct (~5.9 m/s catch-up, calling
the xRunAnimSpeed multiply a misread), while the implementation multiplied
by RunAnimSpeed citing ACE. Settled against the binary, not the pseudo-C:

- BN pseudo-C (acclient_2013_pseudo_c.txt:305127) renders get_max_speed as
  void with a bare `this->my_run_rate;` because it DROPS x87 instructions.
- Disassembling the PDB-matched v11.4186 binary at VA 0x00527cb0: all THREE
  return paths end `fld <rate>; fmul dword ptr [0x007C8918]; ret`, and the
  .rdata dword at 0x007C8918 is 4.0f. Sibling get_adjusted_max_speed
  (0x00527d00) carries the same trailing fmul. Verifier committed at
  tools/verify_un2_fmul.py (PE parse + byte decode, rerunnable).
- Retail paths: weenie null -> 1.0 x4; InqRunRate ok -> queried x4;
  InqRunRate failed -> my_run_rate x4. ACE MotionInterp.cs:665-676 matches.

Changes:
- Doc-comment rewritten: the implementation is retail-correct; the catch-up
  speed 2 x get_max_speed ~= 23.5 m/s at run 200 IS retail. The 1-Hz
  remote-blip symptom the old comment attributed to this multiply is
  therefore UNEXPLAINED by it (if it recurs: #41 family, not this).
- Weenie-null path aligned to retail's LITERAL 1.0 default (was MyRunRate).
- Tests re-pinned to the three retail paths (the old NoWeenie test pinned
  the non-retail fallback).
- Register: UN-2 row deleted per the retire rule (6 -> 5 UN rows);
  shortlist renumbered.

This is the 2nd confirmed instance of the BN x87-dropout artifact class
(memory: feedback_bn_decomp_field_names) deciding a register row.
