The bundled skill file was a frozen 542-line copy that only updated on
plugin re-release. Replace it with a thin pointer to the server-side
resource `skill://methodology`, so skill-content changes propagate
without requiring users to reinstall the plugin.
- skills/oci-deal-accelerator/SKILL.md: reduced to ~40-line stub that
directs Codex to read skill://methodology first, with a minimal
tool table and fallback behavior if the MCP is unreachable
- .codex-plugin/plugin.json: bump to 0.2.0 (breaking change in what
the plugin ships; Codex treats new versions as new cache entries)
- .gitignore: ignore Codex CLI's local .codex state file
