* feat(cli): Codex CLI launcher + setup commands
Two new CLI subcommands mirroring the `launch`/`configure` pattern, for driving the
OpenAI Codex CLI against OmniRoute:
- `omniroute launch-codex` — boots OmniRoute (if needed) and launches Codex CLI
pointed at it (local or remote VPS), with no manual env/config editing.
- `omniroute setup-codex` — generates ~/.codex profile files from OmniRoute's live
model catalog.
Registered in the command registry; en.json + pt-BR.json locale sections added
(keeps the cli-i18n-catalog top-level parity gate green). CODEX-CLI-CONFIGURATION.md
refreshed. Consolidated from work-in-progress that was uncommitted on the shared
checkout; reconstructed on release/v3.8.30.
* chore(vscode): reduce git repo-detection overhead for nested worktrees
Disable VS Code's git auto-repository-detection / submodule scan / autofetch so the
Source Control view stops indexing the ~44 nested repos (worktrees + _references/*
+ _mono_repo/*), which caused constant "validating" churn. Only the root repo is
tracked. Editor-only settings; no runtime impact.
