claude-fleet-codex v0.10.1 — Renamed to claude-fleet-codex: named for what it is, a Claude Code fleet, not a portable one

Nothing executable changes in this release; it is a patch by the owner's call because every script,
unit and template behaves exactly as in 0.10.0. What changes is what the repo says about itself.

Changed

• agentic-codex is now claude-fleet-codex. Three reasons. The repo runs on Claude Code and on
  nothing else, and the old name did not say so. "Agentic" had stopped meaning anything. And a name of
  the shape claude-…-codex needs a real word between the two — fleet, which is already the repo's
  own vocabulary (fleet-agents, fleet-dormant, the roster) — because claude and codex adjacent
  read as a hybrid of two vendors' products, which this is not. GitHub redirects the old name for
  clones, fetches and links; update your remotes when convenient
  (git remote set-url origin https://github.com/<ORG>/claude-fleet-codex.git). Tags and release
  subjects before this version keep the old name in their text; they are history.
• The claim that brain content ports to another harness is retired. It was stated with an honest
  accounting since 0.7.0 and it stopped being true as the framework grew: CLAUDE.md and its @-imports,
  the auto-memory store and its index cliff that the memory model is built around, the SKILL.md format,
  the sub-agent-based skills (decision-loop, advisor-review, agent-audit), the settings schema and the
  SessionStart hook, and a topic's very identity (a Remote Control bridge) are all Claude Code's. Point
  another harness at a brain and you get Markdown it cannot act on; nothing here was ever exercised
  elsewhere. docs/portability.md is rewritten around the two things that are true: the deployment
  moves between machines (Git as source of truth plus one provisioning step — exercised), and the
  ideas travel — a brain as a Git repo of Markdown on GitHub, a shared governance repo every agent reads,
  one explicit provisioning boundary, persistent agents as supervised services under separate Unix users,
  a nightly memory mirror, a structural drift check, a dead-man's switch, decision records with a
  human-gated autonomy line. Rebuild those on any harness; do not copy these files to one. The README,
  architecture.md, config-model.md, reference-architecture.md, the brain template's README and the
  shared bootstrap no longer promise otherwise.
