Introduce statically-enforced 'Rocket' phasing. The core 'Rocket' type is parameterized: 'Rocket<P: Phase>', where 'Phase' is a newly introduced, sealed marker trait. The trait is implemented by three new marker types representing the three launch phases: 'Build', 'Ignite', and 'Orbit'. Progression through these three phases, in order, is enforced, as are the invariants guaranteed by each phase. In particular, an instance of 'Rocket' is guaranteed to be in its final configuration after the 'Build' phase and represent a running local or public server in the 'Orbit' phase. The 'Ignite' phase serves as an intermediate, enabling inspection of a finalized but stationary instance. Transition between phases validates the invariants required by the transition. All APIs have been adjusted appropriately, requiring either an instance of 'Rocket' in a particular phase ('Rocket<Build>', 'Rocket<Ignite>', or 'Rocket<Orbit>') or operating generically on a 'Rocket<P>'. Documentation is also updated and substantially improved to mention required and guaranteed invariants. Additionally, this commit makes the following relevant changes: * 'Rocket::ignite()' is now a public interface. * 'Rocket::{build,custom}' methods can no longer panic. * 'Launch' fairings are now 'ignite' fairings. * 'Liftoff' fairings are always run, even in local mode. * All 'ignite' fairings run concurrently at ignition. * Launch logging occurs on launch, not any point prior. * Launch log messages have improved formatting. * A new launch error kind, 'Config', was added. * A 'fairing::Result' type alias was introduced. * 'Shutdown::shutdown()' is now 'Shutdown::notify()'. Some internal changes were also introduced: * Fairing 'Info' name for 'Templates' is now 'Templating'. * Shutdown is implemented using 'tokio::sync::Notify'. * 'Client::debug()' is used nearly universally in tests. Resolves #1154. Resolves #1136.
