Nicky LeachandPaperclip 821573ede8 refactor(adapter-utils): extract the shared workspace-restore teardown factory (#12196)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - Agent adapters run workspace restore steps when an ACP run ends.
> - Claude, Codex, and Gemini each kept a near-identical teardown
closure.
> - Duplicate closures require the same defect fix in three files.
> - This pull request adds one shared workspace-restore teardown factory
and keeps each adapter's message strings.
> - The benefit is one tested restore-failure path with the same output
and outcome for all three adapters.

## Linked Issues or Issue Description

**What existing behavior does this improve?**

The Claude, Codex, and Gemini ACP adapters restore the workspace during
teardown and report restore failures with an allowlisted message.

**Subsystem affected**

`packages/adapters/` and `packages/adapter-utils/`.

**Current behavior**

Each adapter keeps a near-identical closure. The closure logs a start
line, restores the workspace, classifies errors, and logs a fixed
failure line.

**Proposed behavior**

A shared `createWorkspaceRestoreTeardown` factory owns the common steps.
Each adapter passes its staged runtime, log sink, start line, and
failure prefix.

**Reason and benefit**

The shared factory removes duplicate error handling. One tested
implementation now preserves the existing output and outcome for all
three adapters.

**Breaking changes**

None. The refactor preserves the emitted lines and returned outcomes.

**Additional context**

This pull request contains no public issue reference because no related
public issue was found.

## What Changed

- Add `createWorkspaceRestoreTeardown` to `packages/adapter-utils`.
- Move the shared restore, classify, and allowlisted log flow into the
factory.
- Update the Claude, Codex, and Gemini ACP adapters to call the factory.
- Add a table-driven test for all three message pairs.
- Keep one end-to-end restore-failure regression test per adapter.

## Verification

- `pnpm --filter @paperclipai/adapter-claude-local typecheck`
- `pnpm --filter @paperclipai/adapter-codex-local typecheck`
- `pnpm --filter @paperclipai/adapter-gemini-local typecheck`
- `npx vitest run
packages/adapter-utils/src/workspace-restore-teardown.test.ts`
- `npx vitest run
packages/adapter-utils/src/workspace-restore-merge.test.ts`
- `npx vitest run packages/adapters/claude-local/src/server/acp.test.ts`
- `npx vitest run packages/adapters/codex-local/src/server/acp.test.ts`
- `npx vitest run packages/adapters/gemini-local/src/server/acp.test.ts`
- Continuous integration must pass before merge, except for the known
pre-existing failures listed in the handoff.

## Risks

Low risk. This change moves shared code without changing behavior. The
adapter-specific message strings remain unchanged.

## Model Used

OpenAI GPT-5, exact model ID `gpt-5`, tool use and code review
assistance. The context window size was not provided by the runtime.
