docs(readme): refresh Gemini CLI section to reflect v0.0.11 hook fix

[slashben]

Summary

PR #30 made the SessionStart hook portable across Claude Code and Gemini CLI (shipped in v0.0.11). The README's Gemini CLI subsection was never updated to reflect this.

Old:

Add this repo as an extension. The Gemini extension loads the same skills as the Claude plugin from `skills/`. Install the binary first (see the next section).

This is now wrong on two counts:

1. No actual install command shown.
2. "Install the binary first" — under v0.0.11, the SessionStart hook auto-installs the binary on first session under Gemini, exactly as it does under Claude.

New:

• Shows the verified install command (`gemini extension install https://github.com/armosec/armoctl\`).
• Notes the GitHub-Releases-asset 404 fallthrough and the `git clone` fallback prompt (matches what users actually see, and matches the docs-hub gemini-cli.md).
• States that the same SessionStart hook handles binary install + version pinning under Gemini.

The matching change in the docs hub (`readme-armo-hub-docs/docs/Integrations/ai-agents/gemini-cli.md`) was pushed live to the `v2.0` branch as commit `94cc42c` since that's the live ARMO docs source.

Test plan

• `grep -n 'session-start\|SessionStart\|hook\|0\.0\.10\|0\.0\.11' README.md` — no remaining stale references in the Gemini section.
• After merge: render on github.com/armosec/armoctl, confirm the new code fence renders.

No `release` label — docs-only.

Summary by CodeRabbit

Pull request overview

Updates the README’s Gemini CLI onboarding docs so they match the current cross-agent plugin behavior introduced with the shared SessionStart hook. In the broader codebase, this keeps the public install guidance aligned with the actual Gemini extension manifest and hook-based binary management flow.

Changes:

• Adds the concrete Gemini extension install command.
• Replaces the outdated “install the binary first” guidance with the current hook-driven install/update behavior.
• Documents the current Gemini install fallback flow users see when the release-asset fetch misses and Gemini offers a repo clone.
