    Database integrity improvements

    This release includes a significant database migration that addresses
    longstanding issues with the database schema and data integrity that has
    accumulated over the years. The migration introduces a schema.sql file as the
    source of truth for the expected database schema to ensure new migrations that
    will cause divergence does not occur again.

    These issues arose from a combination of factors discovered over time: SQLite
    foreign keys not being enforced for many early versions, all migrations being
    run in one large function until version 0.23.0, and inconsistent use of GORM's
    AutoMigrate feature. Moving forward, all new migrations will be explicit SQL
    operations rather than relying on GORM AutoMigrate, and foreign keys will be
    enforced throughout the migration process.

    We are only improving SQLite databases with this change - PostgreSQL databases
    are not affected.

    Please read the PR description for more technical details about the issues and solutions.

    SQLite Database Backup Example:

    # Stop headscale
systemctl stop headscale

# Backup sqlite database
cp /var/lib/headscale/db.sqlite /var/lib/headscale/db.sqlite.backup

# Backup sqlite WAL/SHM files (if they exist)
cp /var/lib/headscale/db.sqlite-wal /var/lib/headscale/db.sqlite-wal.backup
cp /var/lib/headscale/db.sqlite-shm /var/lib/headscale/db.sqlite-shm.backup

# Start headscale (migration will run automatically)
systemctl start headscale

    DERPMap update frequency

    The default DERPMap update frequency has been changed from 24 hours to 3 hours.
    If you set the derp.update_frequency configuration option, it is recommended
    to change it to 3h to ensure that the headscale instance gets the latest
    DERPMap updates when upstream is changed.

    Autogroups

    This release adds support for the three missing autogroups: self
    (experimental), member, and tagged. Please refer to the
    documentation for a detailed
    explanation.

    autogroup:self is marked as experimental and should be used with caution, but
    we need help testing it. Experimental here means two things; first, generating
    the packet filter from policies that use autogroup:self is very expensive, and
    it might perform, or straight up not work on Headscale installations with a
    large number of nodes. Second, the implementation might have bugs or edge cases
    we are not aware of, meaning that nodes or users might gain more access than
    expected. Please report bugs.

    Node store (in memory database)

    Under the hood, we have added a new datastructure to store nodes in memory. This
    datastructure is called NodeStore and aims to reduce the reading and writing
    of nodes to the database layer. We have not benchmarked it, but expect it to
    improve performance for read heavy workloads. We think of it as, "worst case" we
    have moved the bottle neck somewhere else, and "best case" we should see a good
    improvement in compute resource usage at the expense of memory usage. We are
    quite excited for this change and think it will make it easier for us to improve
    the code base over time and make it more correct and efficient.
