Update the rust toolchain version to 1.85.
Note that this is not the latest, however, it is the latest available in nixpgs,
so this version is good enough for now.
When the `rad inbox` command would come across a reference name that
it did not recognise as a `Cob` or `Branch`, then it would fail with
an `Unknown` error.
Instead, add an `Unknown` variant to `NotificationKind` which can be
displayed in the `inbox` CLI, by using the `--show-unknown`
flag. Otherwise, it will be skipped and the inbox will work as usual.
While refactoring, the `TypedId` type is used for the `Cob` variant to
simplify some of its uses.

Shows you updates on local repositories.
Included here is a basic implementation of a notification system. A new
database is created and updated after every fetch, with refs that have
changed.
The `rad inbox` command can then list items in the database and delete
them.
