Application lifecycle manager enforcing a three-phase init/wire/start sequence with reverse-order graceful shutdown and per-component stop timeouts.

What's included:
- `Component` interface (OnInit / OnStart / OnStop) and `Hook` type for BeforeStart wiring functions
- `Launcher` interface with Append, BeforeStart, Run (blocks on SIGINT/SIGTERM), and idempotent Shutdown(ctx)
- `New(logger, opts...)` constructor with configurable ComponentStopTimeout (default 15 s); no global state

Tested-via: todo-api POC integration
