This is a large change that introduces transport encryption via
a Noise_XK handshake. The inner `Service` now works directly
with `NodeId` and doesn't need to interact with socket addresses.
The transport logic takes place in `wire::transport`, and the
established sessions are passed down to `Service`.
Note that the i/o implementation in the `poll-reactor` crate still
needs testing, and there is still work to be done to integrate the
Git transport as part of this architecture.

Restrict message size decoding by limiting Message's vector size.
Introduce the BoundedVec type to do this on the type level for
convenience and clarity.

Avoid wasting persistent memory by cleaning up stale routing entries
when the routing table is considered constrained. Limit pruning to
improve resiliency in the face of long intervals between service
downtimes.

Include the node's IP address in the Node's announcements. Source it
from the service's configuration which can assumed to be populated with
default values when available.

In interactive (user) contexts, use `try_sign` instead of `sign`.
We also revisit the `Profile` by adding a `signer` method that can
fail, eg. if we couldn't connect to ssh-agent.
Finally, we replace `UnsafeSigner` with `MemorySigner`, which makes
use of `ssh::Keystore`.

The changes in this commit are all intertwined and it was hard to
split them into smaller commits:
* Use custom transports everywhere
Instead of `file://` and instead of using a child process for fetching
and pushing; we go through our custom transports, which use the `rad://`
and `heartwood://` schemes.
* Introduce a 'mock' remote transport
To test the remote transport without needing to spawn TCP streams,
we add a mock transport that works between storages on the file
system.
* Get rid of node's `git-url`
Instead of git urls, nodes simply use their node-ids to replicate.
