fix(codex): use elevated Windows sandbox

@@ -17,7 +17,7 @@ Codex receives Caveman through its native plugin adapter. Humanizer, Impeccable,
 On Windows, installation and update repair the known Caveman 1.0.0 hook launcher in setup-owned Codex installations so it resolves the plugin path under PowerShell as well as Command Prompt. Custom commands and foreign installations are preserved. Review the changed hook definitions in Codex `/hooks`; setup does not grant hook trust automatically.
 
 
-Normal installation and update ask whether to enable Flashbang, apply the custom status line, and enable optional local QMD search (Yes/No/Auto, disabled by default). Local search runs [QMD](https://github.com/tobi/qmd) (`@tobilu/qmd@2.8.3`, Node.js 22 or newer, `npm`) with Qwen3-Embedding-0.6B, Qwen3-Reranker-0.6B, and QMD Query Expansion 1.7B. Auto benchmarks GPU first, then CPU, and enables search only when median search latency is at most 5 s and embedding runs at least 20 chunks/s. While it is enabled, both clients receive the `semantic-search` skill, which the general rules require for questions whose identifiers are unknown; disabling local search removes the skill and its instruction line. The skill calls `qmd-search.mjs`, which reuses a background daemon on loopback 127.0.0.1 protected by a per-start token; the daemon keeps the models loaded and exits after 30 idle minutes (`QMD_IDLE_MINUTES`). A SessionStart hook warms the index and daemon in the background. Models and the index live in `$XDG_CACHE_HOME/qmd` (default `~/.cache/qmd`); the Codex `writable_roots` cover only `~/.cache/qmd`, so a custom `XDG_CACHE_HOME` needs its own writable root. Under the Codex sandbox, which has not been verified, the wrapper falls back to the slower QMD CLI path when the sandbox blocks loopback connections or starting the daemon. Repository collections skip git-ignored paths; the daemon keeps that list as the collection's `ignore` entry in QMD's `index.yml`. The setup saves and restores a user's own QMD `models:` block, and removal touches only the setup-owned package, models, and repository collections; foreign installs and collections survive. Updating migrates from the earlier Python stack by removing `~/.my-ai-configuration/semantic-retrieval/` and old QMD extension ledger records. Quickupdate reuses the saved shell, client, status line, Flashbang, local search, and extension choices without opening menus. Disabling the status line removes its custom setting and setup-owned Claude script. Only successful runs save selections; dry runs do not update extensions or local search. Install and update do not modify the Codex or Claude CLI installations.

Native Windows packages select the recommended elevated Codex sandbox; its setup can require administrator approval (see [Configuration](configuration.md#permission-defaults)). The previous unelevated mode reproduced `spawnSync git EPERM` during repository-root discovery, before the CLI fallback could run. Runtime search under the elevated mode still needs verification after applying the configuration and starting a new session. The wrapper falls back to the slower QMD CLI path for daemon failures, but that path also needs child-process pipes. Repository collections skip git-ignored paths; the daemon keeps that list as the collection's `ignore` entry in QMD's `index.yml`.

 Plugin installation requires the corresponding client CLI, network access, and any authentication required by the plugin. Context7 may open an OAuth flow. Codex or plugin hooks may require a trust review in `/hooks`. The scripts never install plugins during a build or doctor run and never install them when `--dry-run` or `-DryRun` is used.
