✨ PR Review

The PR adds PR context to GitHub step summaries, but the implementation has fragile JSON parsing that could cause workflow failures.

2 issues detected:

🐞 Bug - Multiple nested fromJSON operations without validation can cause workflow failures if the payload structure is unexpected.

Details: The step performs multiple nested fromJSON calls without error handling or validation. If the client_payload is malformed JSON or missing expected fields, the entire workflow will fail.
File: docs/downloads/gitstream.yml (39-41)

🧹 Maintainability - The single line contains multiple complex expressions that are hard to parse visually and maintain.

Details: The echo command contains an extremely long line with repetitive complex JSON parsing expressions that make the code difficult to read and maintain.
File: docs/downloads/gitstream.yml (41-41)
