[codex] Use ContextForge for have workflows

[willgriffin]

Summary

• replace the long local Claude/Codex workflow bodies with thin ContextForge adapters
• add Codex skills/ entries for have:ship and have:review-cycle
• document ContextForge as the workflow source of truth and sync Codex plugin cache version 0.1.1

Why

Codex does not ingest plugin commands/ as slash commands. The Codex-visible surface needs skills, while Claude can keep the existing command entry points. The actual workflow bodies now live in ContextForge so prompt/workflow edits can go live without redeploying this repo.

ContextForge resources store the workflow markdown as base64 because the default content scanner rejects shell-heavy markdown. The adapters load have-ship / have-review-cycle, read the backing resource, decode the payload, and follow the decoded workflow.

Validation

• python3 -m json.tool on changed plugin and marketplace manifests
• bash -n install.sh
• uv run --with PyYAML python /Users/will/.codex/skills/.system/plugin-creator/scripts/validate_plugin.py /Users/will/.codex/worktrees/have-config-command-skills/codex/plugins/have
• git diff --check
• live ContextForge MCP check confirmed prompts have-ship, have-review-cycle
• live ContextForge MCP check confirmed resources have://happyvertical/workflows/ship, have://happyvertical/workflows/review-cycle
