docs(fleettools): carry the operator's military-time convention into the Codex/Grok bootstrap

Operator directive 2026-09-24: clock times are written in 24-hour local
(US Pacific) format, four digits, no colon. Claude seats get it from the
global CLAUDE.md (dotfiles fe63a67). Codex (~/.codex/AGENTS.md) and Grok
(~/.grok/rules/00-fleettools.md) read this file through symlinks, so the
same rule goes under Non-negotiables here.
