harness: fleet-wide functional-error + correction + friction logging

Add .claude/scripts/log-skill-error.sh — the canonical agent error log helper
(writes errorlog.md in DATE | MACHINE | skill | [type] error format, soft-fails).
Three categories: execution failures (default), user corrections (--correction),
and preventable self-inflicted friction (--friction; cite ref= when it repeats a
documented gotcha). Goal: stop paying tokens twice for the same avoidable mistake.

- CLAUDE.md: make logging mandatory for all skills + corrections + friction.
- skill-creator: new skills must wire in the helper (guidance + checklist).
- Retrofit every skill script's genuine failure branches to call the helper
  (b2/bitdefender/mailprotector/packetdial/coord python CLIs; remediation-tool
  + onboard365 bash; vault, rmm-auth, post-bot-alert, agy, grok, 1password,
  run-onboarding-diagnostic). Handled conditions + self-tests left alone.
- errorlog.md: broaden header to cover skills + harness + corrections; seed this
  session's corrections (INKY, Mail.Send token-audience, omnibox-strictness) and
  friction (git-bash /tmp, env-persistence, argv-limit, PowerShell var-case).
