Preserve tool annotations and output schema through vmcp (#4090)

Preserve tool annotations and output schema through vmcp pipeline

MCP tool annotations (readOnlyHint, destructiveHint, idempotentHint,
openWorldHint) were silently dropped during vmcp aggregation, and
OutputSchema was never populated from backends. This blocks downstream
authorization profiles that need annotation data.

Add ToolAnnotations type to vmcp domain model and propagate both
Annotations and OutputSchema through the full pipeline: backend
query → tool adapter → conflict resolvers → merge → SDK adapter.
