fix(mcp-server): run prisma generate in packages-release workflow (#299)

* fix(mcp-server): remove @prisma/client import to fix CI build

The packages-release workflow installs with --ignore-scripts and never
runs prisma generate, so the Prisma namespace is unavailable at build
time. The satisfies Prisma.* annotations were compile-time-only guards
with no runtime effect; removing them unblocks the npm publish.

* fix(mcp-server): remove all @prisma/client type imports for CI build

The packages-release workflow never runs prisma generate, so the Prisma
namespace is unavailable at build time. All satisfies/variable annotations
referencing Prisma types were compile-time-only; dynamic where objects
are widened to Record<string, unknown>.
