[Enhancement] 灵感 Flow 推送

[CubePlus1]

背景

实现同一个 Inspiration bundled plugin 的第二阶段：把已记录灵感通过确定性、可解释的 Flow 重新带回当前注意力。

已确认范围

• 手动 next 与定时 Flow 共用一个选择器
• 标签、项目、生命周期状态筛选
• 冷却期、quiet hours、每日上限、snooze、lastSurfacedAt
• 持久化 delivery ledger、唯一 dedupe key、通知失败与重启恢复
• 用户动作限定为：查看、继续编辑、保留、稍后、归档
• Flow 通知经 PluginContext.service("notifications.send")；本任务只定义最窄本地接口并 mock

明确边界

• [Enhancement] 灵感记录 #33 与 [Enhancement] 灵感 Flow 推送 #34 是同一个 Inspiration 插件的两个阶段，不是两个插件。
• Inspiration 与 Schedule 完全独立：不查询、创建、转换、关联日程，不调用 schedule API，不建立跨插件表关系。
• snooze 只改变 Flow 投递资格，不改变灵感本体的保留/归档语义。
• 首版不用 AI/embedding，不保存截图、prompt 或回复正文。

Implemented and accepted on branch codex/inspiration-plugin.

• Feature commit: 3ab8946
• Tracking/docs: 9df7561
• Trellis archive: 6e42f20
• Flow: shared deterministic manual/scheduled selector, quiet hours/cooldown/daily limit/snooze, durable dedupe ledger, attempts, stale reservation recovery, outcomes, CLI/Web/report.
• notifications.send remains a narrow lazy Host-service dependency owned by the separate notifications worktree; failures are ledgered without degrading Capture.
• Verification: full suite/build/typecheck and real PostgreSQL dedupe/CAS/restart/abort integration; independent SOL High check has no remaining P0/P1/P2.

Reopened for a required notification-contract repair before final completion. Official baseline commit 29fe6c3 has been cherry-picked into codex/inspiration-plugin as 8484b48; Inspiration is being updated to the SDK function-valued PluginNotificationSend, notifications:send permission, per-channel result ledger, and real PluginHost integration tests. Existing feature commit 3ab8946 will not be rewritten.

Notification contract repair is complete and independently reviewed on codex/inspiration-plugin.

• Official capability source: original 29fe6c3, audit-preserving cherry-pick 8484b48
• Inspiration repair: 592bdb0
• Trellis rearchive: 5fb4bef (archive path normalization c21a40e)
• Manifest now declares notifications:send; Flow uses SDK PluginNotificationSend as a bare function and sends only {title,message}.
• Delivery-owned dedupe/entity IDs never cross Core; bounded mac/ntfy results persist via migration 005.
• Verification: 149 tests (148 pass, 1 existing skip), PostgreSQL 2/2, typecheck/build/diff check, official baseline post-cherry-pick diff zero, independent SOL High review with no remaining P0/P1/P2.

Known non-blocking risk: the narrow crash window after external send but before ledger finalize remains at-least-once because the official Core request intentionally has no dedupe key.

Reopened for PR #36 Code Review reliability fixes on codex/inspiration-plugin: at-most-once notification dispatch, settings-version/interval race, composite delivery cursor, strict offset-aware date validation, manual failed-outcome handling, and real PostgreSQL regressions. Existing commits remain intact; a new additive fix commit will be reported after independent review.
