v0.12.0

Added

• Full typed task discovery for Hubuum server v0.0.16 in both async and blocking
  clients: resource, revision, lifecycle, timestamp, operation-option, output,
  cancellation, and trace filters, including multiple kinds and statuses.
  All filters support cursor pagination through page, all, pages, and
  items, with local validation of incompatible combinations.
• Typed retained import/export/backup options and outcomes, explicit resource
  targets, and rebuild, remote-call, and schema-validation details. Unknown
  historical facts remain optional; output state distinguishes unknown,
  available, expired, and not produced.

Changed

• This release targets Hubuum server v0.0.16 at the existing immutable image
  sha256:37b3299edd845a0c2aa7772d7d68565233ac8c1802bc44be3fb4bbc6dfa8778e.
  The 220-operation contract now reconciles 79 Rust wire models. The complete
  pinned library and downstream-consumer suites passed, including all four
  restore/recovery variants. Features, Rust 1.88, and locked dependency versions
  remain unchanged after checking all compatible dependency updates.

Breaking changes and migration

• Breaking Rust API: ImportTaskDetails, ExportTaskDetails, and
  BackupTaskDetails gain optional retained fields; TaskDetails gains
  reindex, remote_call, and schema_validation. Add retained: None or
  the three new None fields to existing literals, or use the new
  ..Default::default() support. Add .. to exhaustive destructuring patterns.
  Reading existing fields and decoding historical responses remain supported.
• Invalid typed task discovery queries now fail locally with
  ApiError::InvalidTaskQuery before transport. Select compatible task kinds,
  include class_id for revision filters, use nonempty kind/status sets, and
  ensure timestamp bounds and terminal-status selections agree. Unknown
  response fallbacks are rejected as filters except the server-supported
  TaskOutputDiscoveryState::Unknown.
