Implements #5.

RED-first contract: argv-only execution, explicit allowlist, root-confined cwd, bounded env/stdin/output/runtime, structured timeout and truncation evidence, and no shell interpolation.

Zara Core #371 is now completed. Current Core supports plugin-declared zara_requires_approval=true metadata through the canonical principal-scoped ToolApprovalController; callers/model input cannot downgrade it and duplicate registration fails closed. shell.run uses that canonical contract and this plugin introduces no second approval path.

Registry publication is included so zara-shell receives the generated validator, Nix package, plugin tests, installed-runtime compatibility, and lifecycle gates derived from plugins.json.

The generic bounded runner remains deliberately narrow; higher-level sysadmin/coding/desktop behavior stays in their domain plugins.

Zara Core #371 is now completed. Current Core supports plugin-declared `zara_requires_approval=true` metadata through the canonical principal-scoped `ToolApprovalController`; callers/model input cannot downgrade it and duplicate registration fails closed. `shell.run` uses that canonical contract and this plugin introduces no second approval path.
