Breaking changes to the naming: Process -> Agent, Fiber -> Job, Task -> Continuation. Updated the docs.

Cleaned up dependencies and binaries, improved examples in the documentation, renamed `Once` to `Lease` and `NFT` to `Ephemeral`.

Added the - very basic - Clock example and factored the performance benchmarks into separate functions. Added a benchmark for compilation times of ODEMx, but it's not really usable yet.

Migrated to the 2024 edition. Fixed the control macro not working due to temporary tail expression scope being shortened in the new edition.

Reworked processes and fixed bugs associated with shared data and provenance. It's better but Miri still complains about pools.

Improved the Finite State Machines to produce the correct errors in case of using a wrongly branded token.

Using the thiserror crate to reduce boilerplate for error messages, reworked the `brand` module and renamed it to `fsm` (finite state machine), reworking `Irc` (in progress).

Separation of Unique and Irc in order to make the library sound. Free functions (async and sync) to determine the currently active puck.

Re-introduced lifetimes to the pucks of active traits, allowing the borrow-checker to diagnose more cases of mis-use. Fixed soundness bugs with the Irc-mechanism.
