- A network-lock key is generated if it doesn't already exist, and stored in the StateStore. The public component is communicated to control during registration.
- If TKA state exists on the filesystem, a tailnet key authority is initialized (but nothing is done with it for now).

FS implements Chonk, and given the expected load characteristics (frequent use
of AUM() + ChildAUMs(), and infrequent use of Heads() + CommitVerifiedAUMs()), the
implementation avoids scanning the filesystem to service AUM() and ChildAUMs().

Chonks are responsible for efficient storage of AUMs and other TKA state.
For testing/prototyping I've implemented an in-memory version, but once we
start to use this from tailscaled we'll need a file-based version.
