Starting in macOS 15 Sequoia, macOS daemon UIDs are encroaching on our default UIDs of 301-332. This commit relocates our range up to avoid clashing with the current UIDs of 301-304 and buy us a little time while still leaving headroom for people installing more than 32 users.
This constructor is used for public keys as well.
Don't refer to public keys as secret keys in error
This broke in NixOS#11005. Any number of PathSubstitutionGoals would be woken up by a single build slot becoming available. If there are a lot of substitution goals active, this could lead to us running out of file descriptors (especially on macOS where the default limit is 256).
Slight cleanup.

The daemon process is now moved into a new sub-cgroup called nix-daemon when the daemon starts. This is necessary to abide by the no-processes-in-inner-nodes rule, because the service cgroup becomes an inner node when the child cgroups for the build are created (see LocalDerivationGoal::startBuilder()). See NixOS#9675
Prior to this commit, the unit contained this line:
ExecStart=@share/nix-daemon nix-daemon --daemon
which caused systemd to complain:
Failed to restart nix-daemon.service: Unit nix-daemon.service has a bad unit file setting.
See system logs and 'systemctl status nix-daemon.service' for details.
and had this in the unit output:
Sep 03 13:34:59 scadrial systemd[1]: /etc/systemd/system/nix-daemon.service:10: Neither a valid executable name nor an absolute path: share/nix-daemon
Sep 03 13:34:59 scadrial systemd[1]: nix-daemon.service: Unit configuration has fatal error, unit will not be started.
(Notice how it's trying to execute `share/nix-daemon`, which is unlikely
to exist.)
Now with this commit, the path to the daemon binary is properly set:
ExecStart=@/nix/store/lcbx6d8gzznf3z3c8lsv9jy3j6c67x6r-nix-2.25.0pre20240903_dirty/bin/nix-daemon nix-daemon --daemon

I hardcoded the wrong GID (30001 instead of 30000), but it's better to just pick up the GID from the existing group.
- highlighted example - linked definitions to the glossary (this is a shorter read) - fixed some artefact
this makes it less cumbersome to read and puts the statements in meaningful order.
this should make it more obvious how things are related to each other, and also hopefully expose the historical context without having to say on every corner that these details are accounting for legacy decisions.
