chore: address sanity-check findings

- Revert unintended java/mvnw mode change (644 -> 755) introduced in
  the Java SDK commit; CI runs mvnw with explicit bash and doesn't
  require the exec bit.
- Refresh Rust doc comments left stale after renaming request_mcp_apps
  -> enable_mcp_apps on the user-facing API (session.rs warn helper
  docstring + tracing message; UiCapabilities.mcp_apps cref).
