Viktor's agent-rules cleanup: the org claudeMd now carries only
governance red-lines (RBAC tiers, per-user secrets, Terraform-only,
git audit-trail rules, code-layout detection) and points to
~/.claude/rules/execution.md for the worktree lifecycle, which was
previously duplicated here in full. Settings precedence and the
model key are unchanged. Also refreshes a .gitignore comment that
cited the old execution.md section numbering.
