README: add back hero/problem/workflow images + companion tools table (#413)

Brings back three images that shipped in the previous README and a
companion-tools section with star badges for every helper `gx status`
auto-detects:

- `docs/images/install-hero.svg`            in section 01 (Install)
- `docs/images/problem-agent-collision.svg` in section 02 (The problem)
- `docs/images/workflow-source-control-grouped.png` after section 04 tip
- new section `10 Companion tools` with 8 rows:
  oh-my-codex, oh-my-claudecode, OpenSpec, cavemem, cavekit, caveman,
  codex-account-switcher, GitHub CLI (`gh`) — each linked with an
  install snippet and a `?style=social` star badge to the upstream repo.

Also threads `Companions` into the top nav strip so the section is
discoverable without scrolling through the help tree.

All three image paths use the raw.githubusercontent.com URL pattern so
the images render on both github.com and npmjs.com (relative paths
often break on npm's README panel).

Bumps `@imdeadpool/guardex` 7.0.32 -> 7.0.33 so the next `npm publish`
ships the updated README.
