Add the OAuth client type, its database storage, the scope grant package,
policy tag-ownership exposure, and the state operations backing the v2
OAuth client-credentials flow.
Tailscale's keys API has no separate expire verb: DELETE is the revoke.
Map it to a soft revoke so the key stays retrievable as invalid afterwards
instead of vanishing, matching the SDK and Terraform's expectations.
Add a revoked timestamp to pre-auth keys (migration plus schema), mark a
key invalid once revoked, and have the keys DELETE handler stamp it rather
than destroy the row. A background collector reaps revoked keys after a
configurable retention window (preauth_keys.revoked_retention, default
168h), so the table does not grow without bound.
Give API keys an optional owning user and pre-auth keys a free-text
description, plus the state accessors the v2 API needs to act as a
key's owner and to persist descriptions.
Tagged nodes are owned by their tags, not a user. Previously
user_id was kept as "created by" tracking, but this prevents
deleting users whose nodes have all been tagged, and the
ON DELETE CASCADE FK would destroy the tagged nodes.
Add a migration that sets user_id = NULL on all existing tagged
nodes. Subsequent commits enforce this invariant at write time.
Updates #3077
Add a version check that runs before database migrations to ensure
users do not skip minor versions or downgrade. This protects database
migrations and allows future cleanup of old migration code.
Rules enforced:
- Same minor version: always allowed (patch changes either way)
- Single minor upgrade (e.g. 0.27 -> 0.28): allowed
- Multi-minor upgrade (e.g. 0.25 -> 0.28): blocked with guidance
- Any minor downgrade: blocked
- Major version change: blocked
- Dev builds: warn but allow, preserve stored version
The version is stored in a purpose-built database_versions table
after migrations succeed. The table is created with raw SQL before
gormigrate runs to avoid circular dependencies.

This PR changes tags to be something that exists on nodes in addition to users, to being its own thing. It is part of moving our tags support towards the correct tailscale compatible implementation.
There are probably rough edges in this PR, but the intention is to get it in, and then start fixing bugs from 0.28.0 milestone (long standing tags issue) to discover what works and what doesnt.
