v1.9.3 review fixes: CLA doc ranges, README_RUS, mirror/ODD_INS pins

- pd.py/AGENTS: the rejected '8X' range now reads 0x81-0x83/0x85-0x8F
  (0x84 stays accepted); the 0x40-0x4F vs 0x50-0x5F citations are split
  (chaining is ISO-only, TS 102 221 keeps b5=0); the bit-dense CLA list
  gains 0xE7 (exact set verified).
- README_RUS.md: the invalid-INS note mirrored (the removed odd-LSB rule,
  citation corrected to 5.1.2).
- tests: test_vs_reader_mirror (pd.py <-> tools/vs_reader.py drift guard),
  test_odd_ins_set_pinned, the 0xE7 noise vector, and the 'EX' vector now
  uses STATUS (e2 f2) as TS 102 221 Table 10.5 defines.
- tests/baseline.txt regenerated (test listing only); compare_baseline:
  IDENTICAL.
