Add a non-blocking CI report for sample outputs (PromptProof)

[geminimir]

Describe the feature or improvement you're requesting

I’d like to add a minimal report-only GitHub Action that replays one recorded run and publishes a one-page HTML report per PR. It will:

• Trigger only when the three new files change (no impact on the example code).
• Validate { text: string } and forbid obvious PII via regex.
• Show cost/latency for the recorded run.
• Use seed + runs=3 for stability; fixtures only, no live calls.

Here are the three files:

  "input": { "prompt": "Say hi" },

What maintainers get

A single HTML report artifact per PR (schema/regex/cost summary).
Zero live calls; easy to delete if unwanted.

If this sounds okay, I’ll open a 3-file PR and can tweak the checks/paths to your preference.
