The UIResource interface incorrectly specified `_meta?: UIResourceMeta`
when it should be `_meta?: { ui?: UIResourceMeta }` to match the
resources/read response format and all usage examples throughout the
document.

Replace inline comments with comprehensive TypeDoc comments that explain
the purpose and usage of each property. Add examples and clarify
constraints (MUST/SHOULD) for better developer understanding.

Move metadata field documentation from separate prose section into
TypeDoc comments on the UiResourceMeta interface properties. This
consolidates the documentation and eliminates duplication while making
it more maintainable and IDE-friendly.

Change CSP code block from yaml to typescript fence, add context showing
where csp variable originates (resource.\_meta?.ui?.csp), rename
cspHeader to cspValue for accuracy, and remove Content-Security-Policy:
prefix since the variable holds just the policy value, not a complete
HTTP header.

The tool input and tool result examples now show fully formed JSON-RPC
messages with all required fields (jsonrpc, id/method, result/params) to
better demonstrate the protocol format. Also fixes MDX parsing error in
Client\<>Server heading by escaping angle brackets.

Corrects the indentation of nested block structures (alt, opt, par,
loop) in all four Mermaid sequence diagrams. Content inside nested
blocks is now properly indented relative to the block keywords, making
the hierarchical structure clearer and more readable.

Unquote ui, csp, domain, and prefersBorder properties in the

Changes code blocks for notification examples to use `typescript` fence
instead of `json`. This properly represents TypeScript types (like
Record<string, unknown>, CallToolResult, Partial<HostContext>) without
quotes, matching the format used elsewhere in the specification.
Affected notifications:
- ui/notifications/tool-input
- ui/notifications/tool-input-partial
- ui/notifications/tool-result
- ui/tool-cancelled
- ui/resource-teardown
- ui/size-change
- ui/host-context-change
- ui/notifications/sandbox-ready
- ui/notifications/sandbox-resource-ready

Corrected `resources/notifications/list_changed` to
`notifications/resources/list_changed` on line 208 to follow standard
MCP notification naming pattern (`notifications/{category}/{event}`).

Updates the MCP Apps specification to consistently use the
`ui/notifications/` prefix for all notification methods (e.g.,
`ui/notifications/sandbox-ready`, `ui/notifications/tool-result`). Also
removes trailing whitespace, fixes tab/space inconsistencies, improves
code formatting with proper backticks, and clarifies terminology
throughout the document.

Change from text/vnd.mcp.ui+html to text/html+mcp.
Rationale:
- It's an unregistered subtype, allowed for private use
- The +suffix form indicates MCP-specific semantics (postMessage protocol)
- Content is still valid HTML and can be rendered as-such
- Following RFC 6838, +mcp could be registered as an official suffix

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.
