DottaandPaperclip 53f09cb818 fix: prevent duplicate task creation and recovery loops (#9648)
## Thinking Path

> - Paperclip is the open source control plane people use to coordinate
AI-agent companies
> - Agents, routines, productivity review, and recovery services can all
create or re-trigger work
> - Repeated heartbeats or catch-up cycles can produce duplicate tasks
or repeat recovery actions before prior work is visible
> - The base duplicate-create and routine catch-up coalescing work has
now landed on `master` via related PRs while this PR was being prepared
> - This pull request carries the remaining hardening: bounded
idempotency retention, recovery cooldown/throttle fixes,
productivity-review query batching and ordering fixes, and regression
coverage
> - The benefit is fewer duplicate tasks, safer retries, and enough
provenance to diagnose any future recurrence

## Linked Issues or Issue Description

Agents can retry issue creation after ambiguous responses or
independently recreate the same child title, while recovery and
short-interval routine catch-up paths can repeat before prior work
settles. This can produce visible duplicate tasks and makes the
originating heartbeat difficult to identify.

Related work: Refs #8356 for caller-supplied issue-create idempotency
and Refs #9224 for plugin-scoped issue-create idempotency. Prior related
PR: #6936. The base issue-create deduplication and routine catch-up
coalescing pieces have since landed on `master` via #9650 and #9649;
this PR remains as the follow-up hardening stack on top of those
changes.

## What Changed

- Add 7-day retention for issue-create idempotency claims with indexed,
batch-limited cleanup so the claim table does not grow forever.
- Preserve recovery cooldown intent after terminal recovery actions are
closed, and throttle repeated source-scoped recovery work.
- Batch productivity-review source-activity checks to avoid repeated
per-source queries while keeping the no-action suppression behavior.
- Order productivity-review no-action streak windows by review creation
time, matching the window semantics even when completion timestamps are
out of order.
- Preserve generated issue IDs in route mocks used by backlog/assignment
contract tests.
- Document PR-gardening task deduplication expectations in the company
skill.
- Add focused regression tests for idempotency retention, liveness
recovery cooldowns, and productivity-review
batching/suppression/ordering behavior.

## Verification

- `pnpm --filter @paperclipai/server typecheck` — passed on latest head.
- `pnpm exec vitest run --project @paperclipai/server
server/src/__tests__/productivity-review-service.test.ts
server/src/__tests__/issue-create-deduplication-routes.test.ts
--reporter verbose` — 2 files, 23 tests passed on latest head.
- `pnpm --filter @paperclipai/adapter-utils build && pnpm exec vitest
run --project @paperclipai/adapter-utils --reporter dot` — 30 files
passed, 476 tests passed, 8 skipped.
- `pnpm build` — passed on latest head.
- `pnpm -r typecheck` — passed on the rebased head before the final
productivity-review ordering commit; the latest touched server code is
covered by the server typecheck above.
- `pnpm check:token-gates` — passed.
- `pnpm test:run` — progressed through server, UI, CLI, shared,
skills-catalog, and DB sections, then exposed an adapter-utils
compiled-test fingerprint mismatch before rebuilding adapter-utils; the
adapter-utils project passed after rebuild, and the GitHub split PR
checks passed on the pushed head.

## Risks

- Caller-supplied idempotency replay is now bounded to 7 days; reusing
an old key after retention can create new work, which matches
retry-oriented idempotency semantics.
- Recovery and productivity-review timing changes may suppress redundant
follow-up work; focused tests cover the intended boundaries.
- Advisory locking and idempotency cleanup rely on PostgreSQL-compatible
transaction semantics already used by the production data layer.
- The migration extends the private claim table indexes without
rewriting existing issue rows.

> For core feature work, check [`ROADMAP.md`](ROADMAP.md) first and
discuss it in `#dev` before opening the PR. Feature PRs that overlap
with planned core work may need to be redirected — check the roadmap
first. See `CONTRIBUTING.md`.

## Model Used

- OpenAI Codex based on GPT-5, with reasoning, repository editing,
shell/tool execution, and test execution. Exact model ID and
context-window size are not exposed by the runtime.
