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.

Apply MIME type change from commit 0af1532 to all examples and docs.
The profile parameter follows RFC 6838 recommendations for custom
media types, as MCP Apps is a profile of HTML rather than a new syntax.

Introduce new example implementations to replace simple-host and
simple-server:
- basic-host: Reference host implementation with double-iframe sandbox
pattern for secure UI isolation (outer iframe validates and relays
messages, inner iframe renders untrusted tool UI via srcdoc)
- basic-server-react: MCP server example demonstrating tool registration
with linked UI resources and React UI using the useApp() hook
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.
