DottaandPaperclip c6ee96a3df fix: stop idle MCP event polling (#17036)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - MCP task subscriptions and Dot mailboxes notify external clients
when work changes.
> - Their delivery workers queried SQL every two seconds, including when
no work existed.
> - Those queries prevent idle databases from becoming quiet across many
hosted instances.
> - Existing activity, mailbox, subscription, and delivery records
already preserve the work.
> - This pull request uses committed-write signals and saved retry
deadlines to drive delivery.
> - Idle subscriptions become quiet while startup, retry, drain, and
shutdown recovery remain supported.

## Linked Issues or Issue Description

Related sleep migrations: #15625, #17000, #17008. Searched open PRs and
issues for MCP event sleep/polling work; no duplicate found.

**What happened?**

Each public MCP and Dot event service started a two-second interval. It
checked settings, scanned subscriptions, created delivery receipts,
cleaned expired records, and attempted delivery even without changes.

**Expected behavior**

An empty or subscribed-but-idle service produces no recurring SQL or
network traffic. Committed events trigger prompt delivery. Only
unfinished work retains a retry deadline.

**Steps to reproduce**

Configure a public MCP origin and start the server. Observe recurring
settings queries with MCP disabled, or subscription/queue queries with
it enabled. No incoming task changes are required.

**Paperclip version or commit**

Initially inspected master at
`8b4ab65b1c3d863d282752e83307943720a5c85c`; rebased onto `c2daf906d9`
after master advanced. The only conflict was overlapping imports in the
heartbeat queue; both were preserved.

## What Changed

- Register separate MCP and Dot workers with the existing delivery
coordinator. Remove both unconditional intervals.
- Notify from committed activity, comment, mailbox, subscription, and
experimental-settings writes. Centralize comment insertion in one small
helper so normal callers do not manage recovery state.
- Preserve outer transaction ownership, uncertainty reconciliation, and
requests deferred during drain or standby.
- Restore delivery retry/abandoned-claim deadlines on startup. Scan
subscriptions in pages of 20; drain full source and delivery batches
without another external event. Scope subscription refreshes to their
subscription or shared Dot binding, issue activity to its task, comment
discovery to its company, and mailbox/assignment changes to their
binding. Retry deadlines do not rescan unchanged sources.
- Run expired-record cleanup opportunistically. Preserve on-use expiry
checks and the existing one-time automatic Dot challenge behavior.
- Add real PostgreSQL lifecycle coverage and guarded external test
database options for existing MCP/Dot integrations. Document producers
and the supported writer model.

## Verification

- Final head `e54fb34485921016ef988f7df9cca173a9ebdfc8`: all CI checks
passed (55 successful checks/statuses, one neutral review, two
intentionally skipped Storybook checks). Mergeable with no unresolved
review threads. Greptile: 5/5 on this exact commit; security scan
passed.
- All 284 affected tests passed in one local run after rebasing: 16
real-PostgreSQL lifecycle tests, 24 coordinator/scheduler/standby tests,
84 public MCP tests, 54 Dot runner tests, and 106 interaction-service
tests.
- Server TypeScript passed after refreshing generated Runner/plugin SDK
dependencies from master. Full workspace typecheck and build passed
before the rebase; final CI repeated typecheck and build successfully on
the rebased head.
- Coverage includes SQL/network quiet with configuration and history,
committed writes, outer commit/rollback, drain/standby, retry
restoration, reenable/unsubscribe, concurrent writes, shutdown,
source/delivery/subscription batch boundaries, Dot challenges and
reconnects, native broker fences, comment discovery, and
company-isolated scans.
- CI exposed an existing lock-order test whose insert proxy missed
nested transactions and waited indefinitely. The fixture now observes
nested inserts, preserves the lock assertion, and fails explicitly if
interception is missed. The complete 106-test interaction suite and the
formerly hanging CI shard pass. The warm-standby/settings test doubles
were also updated for the new coordinator/transaction boundaries.
- Earlier fixture failures (required timestamps, cleanup, external
database selection, async waits) were corrected. One existing OAuth
first-poll timing assertion and one E2E company-cleanup race passed on
single reruns; the final full CI run passed without a rerun. No OAuth or
company-deletion behavior was changed.
- The local full `pnpm test:run` attempt could not initialize embedded
PostgreSQL after five attempts. It was stopped; affected integrations
were verified with separate disposable PostgreSQL 17 databases, and
final CI supplied the full-suite result. Embedded-only local skips are
not counted as passes.

## Risks

- Notifications use one live server/database scope. Independent SQL
writers and separate live replicas do not trigger these process-local
workers. Startup recovers durable state; continuous multi-writer
discovery needs a notification/ingress contract.
- Idle physical cleanup waits for startup or another enabled sweep.
Subscription and authorization expiry remain enforced on use.
- Existing delivery claims, retry bounds, signatures, and receipt
deduplication remain in place. No new tables or migrations.
- Host sleep-safety checks remain conservative. MCP/Dot retry deadlines
are not yet covered by Paperclip Cloud's scheduled-wake contract. This
proves worker quiet, not deployed host suspension or fleet savings.

## Model Used

OpenAI Codex (GPT-6), with reasoning, local code execution, and tool
use. The runtime does not expose a more specific model version or
context-window size.
