Merge Risk: Low · previous review b84d1

The article adds guidance for a Java authorization SDK. Two statements should be qualified before publication: PDP failures surface as exceptions that callers must treat as denies, and the claim that expressions can never read credentials may overstate the protection for custom credentials. These are accuracy fixes in the text, and the risk is low.

@draft/an-introduction-to-openid-authzen-and-authzen-enforcer/index.md:
- Line 247: Update the expression-access sentence in the documentation to
specify which recognized credential fields are blocked and warn that
application-defined credentials, such as custom API-key headers, may still be
readable and must not be exposed to the PDP. Avoid claiming that expressions can
never read credentials.
- Line 192: Clarify the “Fail-closed by default” bullet for direct AuthZenClient
use: state that AuthZenClient.evaluate throws AuthZenException for the listed
PDP failures rather than returning a deny decision, and that callers must treat
the exception as a deny.
