Nicky LeachandPaperclip f9bd0438e1 fix(server): stop terminal workspace reaper starving on oldest candidates (#11238)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - The server runs a scheduled reaper that archives terminal workspaces
after it checks their state.
> - The reaper reads candidates in `updatedAt` order and skips
candidates that do not qualify for archive.
> - The fixed page kept the same skipped candidates at the front, so the
reaper did not inspect later eligible workspaces.
> - This pull request adds a keyset cursor and a throttled log for
sweeps that archive no workspace.
> - The benefit is that the reaper inspects all candidates over time and
reports an inert sweep.

## Linked Issues or Issue Description

**What happened?**

The terminal workspace reaper inspected a fixed page of old candidates.
Ineligible candidates stayed in that page, so the reaper skipped later
eligible workspaces on every sweep.

**Expected behavior**

The reaper must inspect each candidate over time and archive every
eligible terminal workspace.

**Steps to reproduce**

1. Create more than 50 terminal workspace candidates.
2. Keep the oldest page ineligible for archive.
3. Place an eligible workspace after that page.
4. Run repeated reaper sweeps.
5. Observe that the later eligible workspace remains unarchived.

**Paperclip version or commit**

Commit `3efdf555e6e14a46747c796c3c554438bfc03261`.

**Deployment mode**

Built from source with the server test suite.

**Installation method**

Built from source.

**Agent adapter(s) involved**

Not adapter-specific (core bug).

**Database mode**

Not database-related.

## What Changed

- Add a keyset cursor that uses `(updatedAt, id)` order across reaper
pages.
- Reset the cursor at the end of the candidate set so the next sweep
starts at the beginning.
- Add a throttled log when a sweep inspects candidates but archives
none.
- Add regression tests for archive delivery and starvation.

## Verification

- `pnpm --filter @paperclipai/server exec vitest run
src/__tests__/execution-workspaces-service.test.ts` — 45 tests pass.
- `pnpm --filter @paperclipai/server exec vitest run
src/__tests__/server-startup-feedback-export.test.ts` — 16 tests pass.
- `pnpm --filter @paperclipai/server typecheck` — clean.

## Risks

Low risk. The change affects only candidate paging and the related
reaper log. The cursor resets after the candidate set, so the sweep
remains periodic.

## Model Used

Codex, OpenAI GPT-5, extended reasoning, tool use, and code execution.
