ADconsole v1.0.0

First public release.

- docs: document the audit log, user offboarding, CSV export and the
  "require a reason for destructive actions" setting across README, docs/
  and CLAUDE/AGENTS.md; note retention for panel_audit
- docs: fill the publishing placeholders (repo URL, security contact,
  issue-template links) and add a semantic-versioning policy
- move agent/contributor context into CLAUDE/ (AGENTS.md + a README);
  root CLAUDE.md is now a thin @-import pointer
- add a favicon (shield-lock, matching the login screen) to the login
  page and the app layout
- CHANGELOG: promote [Unreleased] to [1.0.0]; keep the earlier internal
  build as [0.1.0]
