What

Migrate completed/cancelled thread history from history.jsonl to ocas VariableStore (@uwf/history/<thread-id>).

Why

Phase 4c of issue #11. After this, all persistent state (registry, threads, history) lives in the variable store — no more YAML or JSONL files.

Changes

store.ts

New HISTORY_VAR_PREFIX + sync functions: loadAllHistory, findHistoryEntry, addHistoryEntry
migrateHistoryIfNeeded(): reads history.jsonl → writes variables → renames .migrated
Removed: loadThreadHistory, findThreadInHistory, appendThreadHistory, getHistoryPath

Callers

cmdThreadList/Show/Cancel/Complete, archiveThread, resolveHeadHash all use varStore
archiveThread now sync

Variable schema

Name: @uwf/history/<thread-id>, Value: CAS head hash
Tags: workflow, completedAt, reason (completed|cancelled)

Tests

All updated, new migration test, 403 pass / 0 fail

Ref

Closes #11

LGTM ✅

Phase 4 收尾干净：

history.jsonl append-only → @uwf/history/<thread-id> variable，metadata 用 tags（workflow, completedAt, reason）
appendFile 删除，addHistoryEntry 同步写 variable
findHistoryEntry 用 exactName prefix 查找单条，不需要扫全量
parseHistoryJsonlLine 抽出复用于迁移逻辑，好
迁移逻辑与 4a/4b 一致：检测文件 → 导入 → rename .migrated
loadAllHistory 的 completedAt 用 Number(v.tags.completedAt ?? "0") — tags 只能存 string 所以需要转换，合理

Phase 4 三刀全砍完，YAML + JSONL 全部消灭 ⚔️
