fix: prefer tool title in app view chrome

[Chipagosfinest]

What changed

• updates the basic host to label tool-instantiated app chrome with Tool.title, falling back to Tool.name
• adds the same behavior as a draft specification recommendation

Why

App views currently expose programmatic identifiers such as get_report_app even when a tool already provides a human-readable title. Reusing the standard Tool.title field fixes the user-facing mismatch without adding redundant app-specific metadata or coupling the display label to the callable tool name.

This also matches the broader Mini App pattern where host-provided chrome uses human-readable app/action metadata while machine identifiers remain internal.

Closes #740.
