Marten 9.15.0

Closed issues

• #4942 — sharded tenancy: auto-assign never repaired half-provisioned tenants (PR #4945). findOrAssignTenantDatabaseAsync returned early on an existing assignment row, skipping createPartitionsForTenant + per-tenant event-sequence provisioning — so a tenant whose provisioning was interrupted (assignment committed, partitions missing) failed every write with 23514 forever. Both early-return paths (including a second race-window hole under the advisory lock) now run the same idempotent repair the explicit AddTenantToShardAsync(tenantId, databaseId) overload always ran, guarded to once per process per tenant via the resolution cache.
• #4941 — two-day silent projection outage (closed with full mapping). Root cause was #4942; the invisibility was JasperFx/jasperfx#506/#507, fixed in JasperFx 2.27.0 which this release consumes.

Also in this release

• Bundles the fixed JasperFx.Events.SourceGenerator analyzer (JasperFx/jasperfx#505) — CS1061 compile break for no-parameterless-ctor aggregates with instance Apply returning the aggregate.
• Follow-up enhancement filed as #4944 (database-driven partition sweep via pg_inherits) for the #4943 provisioning-tool scenario.

Verified against Wolverine (full solution + CoreTests/MartenTests/distribution/Http suites, zero failures) and CritterWatch before publishing. Thanks to @erdtsieck for the dump-verified root-cause analysis.
