Converted the HostContext interface documentation from a separate "Field
Descriptions" section to JSDoc-style comments above each field. This
improves consistency with other interfaces in the specification and
keeps documentation closer to the code.

Replace all occurrences of text/html with text/vnd.mcp.ui+html
in the specification and example code for consistency.
The spec already defined text/vnd.mcp.ui+html in the capability
negotiation section but used text/html in other places.
