Release v0.37.0

⚠️ Breaking Changes

The Result.Meta field type has changed from map[string]any to *Meta. Code that directly accesses or sets this field will need to be updated:

// Before (v0.36.0 and earlier):
result.Meta = map[string]any{"key": "value"}
// After (v0.37.0):
result.Meta = &mcp.Meta{AdditionalFields: map[string]any{"key": "value"}}
