/**
 * Regression: issue #2639 — Codex install generated agent TOMLs with stale
 * Claude-specific references (CLAUDE.md, .claude/skills/, .claudeignore).
 *
 * RCA: `installCodexConfig()` applied a narrow path-only regex pass before
 * calling `generateCodexAgentToml()`, bypassing the full
 * `convertClaudeToCodexMarkdown()` + `neutralizeAgentReferences(..., 'AGENTS.md')`
 * pipeline used on the .md emit path. Fix routes the TOML path through the
 * same pipeline and extends the pipeline to cover bare `.claude/skills/`,
 * `.claude/commands/`, `.claude/agents/`, and `.claudeignore`.
