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.

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.
