Revamp showcase to deterministic replay UI and static artifact validation

[ProfRandom92]

Motivation

• Reframe the showcase toward deterministic operational replay validation for long‑horizon AI agents and surface committed artifact evidence instead of invented dashboard telemetry.
• Ensure the static reviewer console is provably reproducible by reading committed JSON artifacts and asserting expected derived metrics and links.

Description

• Add a static data module showcase/app/src/data/benchmarkArtifacts.ts containing committed benchmark card definitions, metric values, and artifact link lists that are intentionally copied from committed JSON artifacts.
• Update showcase/app/scripts/validate-static.mjs to read the new static data and repository artifacts, validate a new set of required phrases, and assert that derived artifact metrics are present in the static data, failing with clear errors if checks are missing.
• Replace the old enterprise showcase UI in showcase/app/src/main.tsx with a focused deterministic replay reviewer console that reads metrics from the static benchmarkArtifacts module, provides artifact links (repoHref), and simplifies the component tree to static metric cards, benchmark cards, pipeline, integrity badges, and artifact explorer.
• Refresh showcase/app/src/styles.css with a redesigned, responsive dark theme, new layout rules, and styles for the new components.

Testing

• Ran the static validation script with node showcase/app/scripts/validate-static.mjs, which executed the phrase and metric assertions and returned success (Deterministic replay showcase validation passed.).
• Performed a local showcase build check with npm --prefix showcase/app run build to verify the app compiles and the updated assets bundle successfully (build succeeded).

Code Review

This pull request refactors the showcase application into a static 'Replay validation console' that surfaces data from committed benchmark artifacts. The changes include a new validation script to ensure data consistency and a simplified React UI. Feedback highlights that the validation script's regex-based checks are brittle and lack benchmark-specific scoping, which could lead to false positives or runtime crashes. Additionally, it is recommended to replace the hardcoded personal repository URL with a configurable or relative path to better suit the project's industrial requirements.
