fix: remove private customer artifacts

[aamir]

Summary

The public repository no longer carries a customer-specific desktop route or customer-derived examples. This removes the orphaned prototype support and adds fail-closed, redacted release scans so protected terms do not need to be committed to public source.

Scope

• Remove the customer-specific UI route and its now-unused styles, schemas, scripts, dependency, and CI step.
• Replace customer-derived fixture names and measured examples with synthetic, workload-neutral values.
• Scan every tracked and packaged path and file, regardless of extension, using a private term-and-collision policy supplied only by an authorized maintainer.
• Require that private policy for release scans while keeping ordinary untrusted pull-request CI secret-free.
• Keep generic benchmark, verifier, trace-export, and eval-authoring behavior unchanged.
• Fix a literal A2A URL rejected by Rust 1.98 Clippy so required CI can validate the cleanup.

This cleans the current tree only. Existing Git history, old pull-request revisions, branch refs, forks, and cached copies remain outside this change and need a separate repository-replacement or history-cleanup decision.

Validation

• npm run check — build, typecheck, and 1,312 tests passed.
• Authorized private current-tree and package release scans passed.
• bun run build in apps/homescreen passed.
• cargo +1.98.0 clippy --all-targets -- -D warnings passed.
• cargo +1.98.0 test — 309 passed, 6 ignored.
• git diff --check passed.
