mtlcl410andClaude Opus 5.5 39b96ccf3d fix(render): a visibility expression decides what an OCMD shows (#2986) ...

An optional content membership dictionary may carry a visibility
expression (/VE, PDF 1.6): [/And e...], [/Or e...] or [/Not e], each e an
optional content group or a nested expression. It takes precedence
over /OCGs and /P (ISO 32000-2 8.11.2.2). hayro-interpret ignored it, so
content under such a dictionary stayed visible when its layers were
hidden in the Layers panel.

Vendored hayro-interpret patch (40) evaluates the expression, nested
up to 32 deep. A malformed expression (unknown operator, /Not without
exactly one operand, /And or /Or without any, an operand that is
neither a group nor an expression, too deep) falls back to /OCGs and
/P as before.
