chore(deps-dev): update google-genai requirement (#44)

Dependabot dep bump (google-genai constraint widened to >=1.0,<3). +1/-1, single file.

History: 6 checks were SUCCESS pre-rebase. Branch updated via GitHub's update-branch endpoint after main moved. --auto enabled to merge once the re-triggered checks clear.

Salvaged as part of github-cleanup-2026-05-18 PR salvage (D2: prefer local pytest, but AgentSuite is a public repo with free hosted runner minutes; --auto lets the existing CI workflow re-verify the rebase without burning operator attention).
