schema-init v0.1.2 -- schema-board, log rotation, better schema-ctl

Ships schema-board: a read-only weight-state board that reads the shm
export rather than the control socket, so it keeps working when the
socket or the desktop is wedged. Needs no root.

Adds a logrotate config plus an example on_calendar rotation timer --
/var/log/schema-init/ previously had no rotation at all.

schema-ctl gains --help/--version and now reports the real connect
error instead of the fallback path errno.

No change to PID 1 behaviour.

schema-init v0.1.1 -- now actually licensed, and packageable

Adds the AGPL-3.0 license text that v0.1.0 shipped without, a
DESTDIR-honouring make install, and an RPM spec for Fedora COPR.

Also fixes CFLAGS being hardcoded: a distro or packager value is now
honoured, which is what made the RPM build possible at all.

No change to PID 1 behaviour.

schema-init v0.1.0 — first tagged release

A minimal PID 1 init system for Linux that supervises services through a
weight-state machine instead of unit files and dependency graphs.

Measured on the tagged build (blakbox, Fedora 44, KDE Plasma, 47 services):
PID 1 holds 3.3-4.0 MB RSS in one thread. Minimal static boot measures
1.2 MB. Binary is 5,607,840 bytes as built, 1,199,144 stripped.

Assets are stripped, produced by make release, with SHA256SUMS.
