docs: align Codex plugin discovery metadata

[yyiilluu]

Summary

• Align Codex plugin metadata with the current claude-smart positioning for Claude Code, Codex, and OpenCode.
• Use the public Preferences / Project-specific skills / Shared skills terminology in user-facing metadata.
• Refresh Codex plugin discovery keywords to match the broader package/plugin keyword set and replace the older playbook keyword with skills.

Test Plan / Validation

• git diff --check
• python3 -m json.tool plugin/.codex-plugin/plugin.json

Marketing rationale

This keeps Codex plugin metadata consistent with the README, npm package metadata, and Claude plugin metadata so developers searching for Codex memory, agent-memory, and self-improving agent tooling see accurate, current positioning.
