HM-Arch v2.0.4

HM-Arch v2.0.4

HM-Arch 2.0.4 is a patch release for the three-agent integration line. It
keeps the v2.0.x Python, npm, and standalone channels aligned while making the
default user-facing install path use the latest stable package.

What changed

• Codex recall hook output now includes
  hookSpecificOutput.hookEventName: "UserPromptSubmit" alongside
  additionalContext, matching the expected lifecycle hook JSON shape.
• Hermes, Claude Code, and Codex installation and memory smoke paths were
  validated together after the v2.0.x integration fixes.
• README and agent setup docs now recommend latest stable install commands for
  normal users:

pip install hm-arch
pipx install hm-arch
npm install -g @hm-arch/installer
npx @hm-arch/installer install hermes
npx @hm-arch/installer install claude-code
npx @hm-arch/installer install codex

Version-pinned installs remain supported when users need reproducible
environments:

pip install hm-arch==2.0.4
npm install -g @hm-arch/installer@2.0.4
