Closes #7896

Add dedicated Linux, macOS, and Windows CI coverage for Bun-only frontend startup. Explicitly install Bun, verify startup without Node and with an outdated Node version, fail CI on missing prerequisites or skipped tests, and record runtime versions.

Confidence Score: 5/5

[Medium impact] The latest change appears safe to merge; no new blocking issues were found.

Summary

Adds required Bun startup checks on Linux, macOS, and Windows, covering both missing and outdated Node installations.

• CI checks Bun frontend startup across three operating systems.

Earlier threads about partial page checks and bare Python commands were manually resolved by somiljain2006 without explanation. somiljain2006 accepted the small repeated assertion blocks because the tests cover different setups and remain easier to read separately; Greptile withdrew that suggestion. No new findings.
