Materialize a (Claude-shaped) plugin dir's skills into <cwd>/.codex/skills/ —
where Codex actually discovers them (validated live: codex reads
<cwd>/.codex/skills/<name>/SKILL.md). This is the Codex analog of Claude's
--plugin-dir: measureTriggerRate hands the runner a pluginDir (the
stubbed/packaged skills), and the Codex runner installs them here before the
turn. Pure fs — unit-testable without a binary.
