Replace hardcoded port assignments and npm scripts with run-all.ts that:
- Auto-discovers example directories and assigns ports
- Passes server URLs to basic-host via SERVERS env var
- Supports start, dev, and build commands
Update basic-host to fetch server list from /api/servers endpoint
and display server names from MCP server metadata.

Change onsizechange handler to use min-width instead of width,
treating the app's reported size as a floor rather than exact.
Use min(Xpx, 100%) to allow shrinking with container.
Also remove outmost max-width constraint and simplify iframe CSS to
allow apps to demonstrate responsive growing.

with Claude Desktop and other MCP clients that use stdio transport.

Some host implementations incorrectly return the full JSON-RPC envelope
(with result, jsonrpc, id fields) instead of just the unwrapped result.
This causes apps using callServerTool() to fail when accessing result.content.
This fix detects wrapped responses and unwraps them automatically.

Not all MCP clients support structuredContent in MCP tool results, so
examples now return data as JSON in content and parse it client-side.
Pattern used:
- Server: content: [{ type: "text", text: JSON.stringify(data) }]
- Client: JSON.parse(result.content!.filter(...).map(...).join(""))

Introduce new example implementations to replace simple-host and

- basic-host: Reference host implementation with double-iframe sandbox
pattern for secure UI isolation (outer iframe validates and relays

Build infrastructure updates:
- Add build:all script and simplify CI/pre-commit to use it
- Add examples:dev for watch-mode development workflow
Also change PostMessageTransport logging from info to debug level.

Change MIME type from `text/html+mcp` to `text/html;profile=mcp-app`
to follow RFC 6838 recommendations for custom media types.
The `+suffix` format (like `text/html+mcp`) is intended for structured
syntax suffixes (e.g., `+json`, `+xml`) that describe the underlying
format. Since MCP Apps doesn't define a new syntax but rather a profile
of HTML, using a profile parameter is more semantically correct.
