Raise gemini-local hello probe timeout to 60s for SSH and E2B targets (#5322)

## Thinking Path

> - Paperclip orchestrates AI agents for zero-human companies
> - The Gemini adapter's environment Test surfaces a hello probe so
operators can confirm the CLI runs end-to-end on the configured target
> - On SSH and E2B sandbox targets the round-trip cost (login-shell
sourcing, network, model warm-up) routinely exceeds the existing 10s
probe timeout, so the probe spuriously fails on environments that are
actually healthy
> - This pull request raises the gemini-local hello probe timeout to
60s, matching the timeout we use for slower-bootstrapping adapters
> - The benefit is the Gemini Test action no longer reports false
negatives on remote targets that need a longer first-run window

## What Changed

- `packages/adapters/gemini-local/src/server/test.ts`: hello probe
timeout raised from 10s to 60s

## Verification

- `pnpm vitest run --no-coverage --project
@paperclipai/adapter-gemini-local`
- Manual: SSH and E2B Gemini hello probes now complete cleanly without
spurious timeouts

## Risks

Low. A 60s ceiling on a non-blocking probe is consistent with sibling
adapters; the only behavior change is a longer worst-case wait when the
probe genuinely hangs.

## Model Used

Claude Opus 4.7 (1M context)
