PRE-RELEASE — Optional @AgentTool annotations and build_runner codegen for intentcall.

/// Smoke harness for catalog → registry wiring in the example app.
///
/// Catalog sources (see `@AgentCatalog` in `demo_host_tools.dart` and `docs/DX_FAQ.mdx`):
///
/// ```text
/// @AgentTool          →  tool implementation + (usually) catalog row
/// handwritten getter  →  tool implementation only
/// catalog row         →  @AgentCatalog list
/// agent_catalog.g.dart →  merge of all three sources
/// ```
///
/// Build time and runtime serve different jobs:
///
/// - **Build / manifest export** — `AgentCatalogGenerator` merges rows into
///   [agentCatalogEntries]. For `@AgentTool` on instance methods it needs a
///   compile-time probe anchor, defaulting to `Host.shared.<getter>CallEntry`
///   (here `DemoHostTools.shared.demoHostStatusCallEntry`).
/// - **Runtime** — the app may register a different live host instance when
///   descriptors match (DI container, per-session state, tests).
///
/// **Apple discovery** — Siri and Shortcuts discover registry **verbs** via
/// `apple.appIntents` + opt-in `apple.appShortcuts` on tools such as
/// `app_demo_set_greeting`. Indexable **nouns** (`@AgentEntity`, Spotlight) are
/// dogfooded in the Flutter showcase, not this dart-only host:
/// `mcp_flutter/flutter_test_app`.
