fix(bitdefender): errorlog rule-compliance + moveCustomGroup param + ASCII-clean code

Finalizing the skill to "done, no errors, all skill rules":
- errorlog compliance: gz.py no longer logs EXPECTED API responses (validation,
  method-not-found, not-configured, rate-limit, expected state) or `raw`/selftest
  runs to errorlog.md. Per CLAUDE.md "do not log expected/handled conditions".
  Verified: selftest + probes leave errorlog unchanged.
- moveCustomGroup: param is `parentId`, not `newParentId` (6th doc-vs-live fix
  caught by a full param-shape audit).
- ASCII-clean code: removed all non-ASCII (em-dashes, U+21D2 arrow) from scripts
  (avoids cp1252 encode errors; aligns with the ASCII-markers rule).
- api-reference updated.

Verified: 18/18 read commands rc=0 live; selftest 75/75; parser builds; ASCII
markers + vault load + errorlog helper present.
