fix: support AI SDK jsonSchema() with .jsonSchema property

Browse source 
Added Strategy 2.5 to schema extraction to handle AI SDK v6's
jsonSchema() wrapper which uses `.jsonSchema` property instead
of `.schema`.

This fixes schema validation errors for @tpmjs/hello and other
packages that use jsonSchema() wrapper.

Error was: "No valid schema found" with keys ["_type", "jsonSchema", "validate"]
Fix: Check for inputSchema.jsonSchema as an object property
