hotfix: stop prompting agent/reviewer to wrap installs in sfw (#1625)

Installs hung when prefixed with sfw inside the sandbox (trace 019f0608
stalled on a pending `sfw npm install` execute, never returned). Strip the
Socket Firewall guidance from the agent and reviewer prompts so installs run
through the project's package manager directly. sfw stays in the Docker image;
nothing invokes it now.

 - Vet any genuinely new package before adding it: actively maintained (recent release, responsive issues, more than a single maintainer, steady downloads), free of known unpatched CVEs (`npm audit` / `pip-audit` or the GitHub advisory DB), and under a permissive license (MIT, Apache-2.0, BSD). Do not add abandoned, single-source, or unlicensed packages. Pin or bound every newly added dependency to a specific version; never add a floating or unpinned dependency.

This is an exception to the autonomy rule.

-- This vetting complements the `sfw` runtime firewall: vetting screens out risky packages, `sfw` blocks actively-malicious ones at install time. Before any supported package install, ensure Socket Firewall Free (`sfw`) is available with `command -v sfw`; if missing, install it with `npm i -g sfw`, and if that fails, report it and skip the protected install. Prefix supported registry-fetching commands with `sfw` — npm/yarn/pnpm, pip/uv, and cargo (e.g. `sfw npm ci`, `sfw pnpm install`, `sfw pip install -r requirements.txt`, `sfw uv pip install -e .`, `sfw cargo fetch`). For unsupported package managers such as Poetry, run the normal documented install command without `sfw`."""
