Refresh FluencyLoop marketplace packages automatically when an agent starts

[baokhang83]

Summary

• Use Claude Code's native startup plugin refresh for marketplace-installed FluencyLoop.
• Add a trusted Codex SessionStart hook that refreshes only FluencyLoop's supplying marketplace
  and installs its latest package.
• Release the change as 0.2.2 and document the one-time bootstrap needed by existing Codex users.

Design and decision

• Design record: docs/fluencyloop/features/refresh-fluencyloop-marketplace-packages-automatically-when/design.md
• Chose host-native lifecycle hooks over restoring install.sh or fluencyloop self upgrade:
  host ownership preserves the active session and keeps automation scoped to FluencyLoop.
• Constitution check: satisfies §1 host lifecycle, §2 session-boundary activation, and §3 narrow
  automation scope.

Validation

• Codex plugin manifest validation
• Claude marketplace manifest validation
• Bash syntax checks and a scoped startup-hook smoke test
• FluencyLoop reviewer view: one journaled session, zero unjournaled commits

Note

Codex asks the user to review the hook once. After trust is granted, updates are checked on every
new Codex session and an installed update becomes active in the following session.
