N1: scopeKey guarded the empty-string VALUE but not the TYPE. A
non-string tenantId (null, 0, false, an object) flowed through
un-normalised, and the adapters disagreed about the result - db
rejects null on NOT NULL, memory accepts it as an unreachable row; 0
and false stringify differently and could collide. Now
`typeof tenantId !== "string" || tenantId === ""` is refused with the
same WRN-AUTHZ-SCOPE error. Added a conformance case covering
null/0/false/{}.
N2: nothing failed if grant() were re-wrapped in db.tx, reintroducing
the shared-connection rollback from C1/C2 - timing-based tests can't
reliably prove a transaction is never opened. Added
db-no-transaction.test.ts: a fake Db with a spied driver.transaction
and statement-recording all/exec, driving every PermissionStore method
and asserting zero transaction calls and no "BEGIN" in any recorded
statement. Verified it fails when grant() is temporarily re-wrapped in
db.tx, then restored.
Also documents two things in db.ts as comments only: the UNIQUE
constraints are now load-bearing for ON CONFLICT/ON DUPLICATE KEY
target inference, and MySQL's VALUES(effect) upsert syntax is
deprecated since 8.0.20 (no MySQL server in CI to catch its removal).

C1/C2: grant() wrapped its delete+insert in db.tx on a shared,
unserialized sqlite connection, so a concurrent bare write from another
method (e.g. revokeRole) got swept into the open transaction and
discarded on rollback - a revoke could report success while the
privilege survived. Also broke concurrent grants on distinct keys
("cannot start a transaction within a transaction"). Replaced with
single-statement upserts (ON CONFLICT / ON DUPLICATE KEY UPDATE),
atomic without a transaction.
I1: assignRole's check-then-act SELECT lost 19/20 concurrent identical
calls to a UNIQUE violation; switched to ON CONFLICT DO NOTHING.
I2: an unrecognised `effect` value was dropped from both the grant and
deny buckets on read. Added a CHECK constraint and made anything not
literally "allow" count as a deny (fail closed).
I3: ensureAuthzTables defaulted to sqlite instead of the Db's own
dialect. I4: scopeKey now refuses an explicitly empty tenantId rather
than treating it as global (shared with the memory adapter). I5: added
migrations.test.ts asserting the generated DDL per dialect, including
MySQL's binary collation on identity columns. M1: DDL is now a
statement list instead of a blob split on a formatting-dependent
separator. M3: declared @wrnexus/db as a workspace dependency.
Extends the conformance suite with four concurrency/empty-scope tests
(23 total, up from 19) that all three adapters now pass.

Adds dbPermissionStore/ensureAuthzTables/authzMigrationSql, backed by
_wrn_authz_assignment and _wrn_authz_grant tables, plus a ./db subpath
export. Passes the identical 19-test store-conformance suite the memory
adapter passes, including tenant-scope isolation.
