Fix Codex skill injection to use ~/.codex/skills/ instead of cwd

The Codex adapter was the only one injecting skills into
<cwd>/.agents/skills/, polluting the project's git repo. All other
adapters (Gemini, Cursor, etc.) use a home-based directory. This
changes the Codex adapter to inject into ~/.codex/skills/ (resolved
via resolveSharedCodexHomeDir) to match the established pattern.

 - Prompts are piped via stdin (Codex receives "-" prompt argument).
 - If instructionsFilePath is configured, Paperclip prepends that file's contents to the stdin prompt on every run.
 - Codex exec automatically applies repo-scoped AGENTS.md instructions from the active workspace. Paperclip cannot suppress that discovery in exec mode, so repo AGENTS.md files may still apply even when you only configured an explicit instructionsFilePath.
-- Paperclip injects desired local skills into the active workspace's ".agents/skills" directory at execution time so Codex can discover "$paperclip" and related skills without coupling them to the user's login home.
+- Paperclip injects desired local skills into ~/.codex/skills/ (the Codex home directory) at execution time so Codex can discover "$paperclip" and related skills without polluting the project working directory.
 - Unless explicitly overridden in adapter config, Paperclip runs Codex with a per-company managed CODEX_HOME under the active Paperclip instance and seeds auth/config from the shared Codex home (the CODEX_HOME env var, when set, or ~/.codex).
 - Some model/tool combinations reject certain effort levels (for example minimal with web search enabled).
 - When Paperclip realizes a workspace/runtime for a run, it injects PAPERCLIP_WORKSPACE_* and PAPERCLIP_RUNTIME_* env vars for agent-side tooling.
