[memory→tinymemory] tinymemory-tools: lifecycle turn hooks, live in-prompt window, date hint #285

Blocked by #280.

For openhuman's memory/lifecycle/hooks.rs (558; tests 638), window.rs (114) and date_hint.rs (77).

• lifecycle::turn::TurnHooks takes over the orchestration:

  • pre-turn timeout, spawn, and degrade-to-no-pack;
  • log-only when the identity has recall off;
  • choosing pre_turn / pre_turn_resumed / pre_turn_dated;
  • post-turn "log and return jobs";
  • compaction recall.

  It also takes TurnPack (render + refusal notice + tag constants), logged_reply (memory_eval/agent.rs:284 has its own copy) and user_turn_index.

• PreTurn gains a resumed flag. It already has in_prompt_from, at and observed_actor. ToolCallSummary becomes ToolCallRef plus a result line.

• lifecycle::window::InPromptFrom: the live in-prompt start index, with atomic fold fingerprints and a ceiling. It has no host dependencies.

• lifecycle::date_hint: the instruction text, parse_range, and a DateHintModel callback trait.

• Seams as traits, so no tokio in this crate: Spawner, Clock, engine resolution, the date-hint model, a jobs sink and a citation sink.

The bus trigger stays in the host (decided: ConversationTurnCommitted → memory::bus).

Done when: the new API is merged with its tests (moved host tests travel with the code), cargo test --workspace and cargo clippy --workspace --all-targets -- -D warnings pass, and a tag is cut so OpenHuman can bump the gitlink. tinymemory-tools stays tokio-free (spawn/clock are traits); schemars only behind an optional schema feature.

Agent brief

• Files to consider: host memory/lifecycle/{hooks,window,date_hint}.rs; upstream tinymemory-tools/src/lifecycle/
• Research: the gaps listed above
• Workflow: an implementing-an-epic step; follow the migrate-to-submodule skill (upstream PR → tag → OpenHuman gitlink bump + delete host copy).
• Subagent: tdd-implementer.
