Record which assistants are tested in the install table

The table rewrite dropped the (Tested) and (Experimental) labels that the per-assistant headings used to carry, leaving nothing in the README to say which of the five had actually been exercised. A Status column restores that without going back to headings, and keeps the same vocabulary fusion-skills uses so the two READMEs can be compared side by side.

Four are marked Tested on evidence rather than assertion: each installed from its own row in this table, then built and deployed an app from the example prompt, and `foundry apps list` confirms all four on the tenant by name. Three went further and released.

Antigravity CLI stays Experimental because it has not been verified, not because it failed. The distinction is stated under the table so a reader knows Tested means an app reached a live tenant and Experimental means the format should work but nobody has watched it happen.

-|-----------|---------|-------------|
-| Claude Code | `/plugin install crowdstrike-falcon-foundry` | [Anthropic](https://claude.com/plugins/crowdstrike-falcon-foundry) |
-| Codex | `codex plugin add crowdstrike-falcon-foundry` | [OpenAI](https://chatgpt.com/plugins) (pending) |
-| Copilot CLI | `copilot plugin install CrowdStrike/foundry-skills` | [GitHub](https://github.com/marketplace?type=copilot-plugins) |
-| Cursor | `/add-plugin crowdstrike-falcon-foundry` | [Cursor](https://cursor.com/marketplace) (pending) |
-| Antigravity CLI | `agy plugin install https://github.com/CrowdStrike/foundry-skills` | [Google](https://antigravity.google/docs/plugins) |

-For local development with Claude Code, use `claude --plugin-dir /path/to/foundry-skills`. These skills follow the [Agent Plugins](https://agent-plugins.org) format; any assistant that reads from `~/.agents/skills/` can discover them.

+**Tested** means the skills were installed using the command above and then used to build and deploy a working app to a live Falcon Foundry tenant, from the example prompt below and nothing else. **Experimental** means it should work, since these skills follow the [Agent Plugins](https://agent-plugins.org) format that all five assistants read, but we have not verified it end to end.
