ci(hermes): fail the e2e when CI has no TinyFish key instead of skipping

[Zechereh]

Change	Why
e2e.sh exits 1 when TINYFISH_API_KEY is empty and CI is set	a silent skip let the e2e pass without any live checks, which is how the Windows setup crash in #57 went uncaught

Local runs without a key still skip the live checks. Missed #59 because it was pushed after the merge.

📝 Walkthrough

When TINYFISH_API_KEY is unset and CI is non-empty, the end-to-end script reports an error and exits with status 1. Outside CI, it retains the existing successful skip.
