v0.1.6

v0.1.6 requires a fresh database. Exception attempt counters now advance on
failure, requested delay, or lease expiry, without consuming an attempt for
deferral or a fresh claim. Existing counters have no automatic conversion.
Both schema versions remain v1, so version checks do not reject mixed builds.
The compatibility round-trip does not verify an existing-database upgrade.

Release changes:

• Completed consumer work is recorded during graceful shutdown. Canceled
  startup alert checks stop without warnings.
• Worker-liveness reports use INFO and name missing components. Update
  bindings that select their old warn routing-key segment to select info.
• CLI environment variables are SQLSTREAMS_DATABASE_URL and
  SQLSTREAMS_SCHEMA. Replace SQLSTREAMS_ADMIN_DATABASE_URL and
  SQLSTREAMS_ADMIN_SCHEMA in existing shell configuration.
• Public configuration structs and copied comments improve editor hover.
  Code importing owning-package config types must use the sqlstreams types
  at client boundaries.
• CLI help and documentation use consistent wording. Conflicting metric
  attribute filters return a usage error. Examples are self-contained, and
  the docs add an Overview board and improved phone navigation.
