fix: clarify native tool use for external agents (#15734)

## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - External agents keep their own tools and app connections.
> - The Paperclip assignment catalog controls the Paperclip bridge.
> - Dot treated a qualification test restriction as a rule for later
work.
> - Existing prompts did not clearly separate these two tool sources.
> - This pull request tells agents to use their own capabilities and
return results to Paperclip.
> - The benefit is that a missing Paperclip app does not block an
available native capability.

## Linked Issues or Issue Description

Related work: #15722 and #15691. I searched open PRs for Dot tool
guidance and found no duplicate.

**What happened?**
After a qualification test, Dot refused a Slack request because the test
Paperclip agent had no assigned Slack app. Dot already had a working
Slack connection in ChatGPT. It carried the test's plugin restriction
into a later task message.

**Expected behavior**
An external agent uses its own available tools, apps, plugins, skills,
and capabilities to complete the current request. It then returns the
result through Paperclip's task reporting and completion tools. The
assignment catalog limits Paperclip calls. It does not disable the
agent's native tools.

**Steps to reproduce**
1. Connect a Dot that has a native Slack connection.
2. Complete a Paperclip qualification task with a restriction scoped to
that test.
3. Send a later task message that requires Slack.
4. Observe that Dot can mistake the Paperclip catalog for its full tool
inventory.

**Deployment mode**
Observed on Cloud staging with the Dot Runner.

## What Changed

- Add shared tool-use guidance for external-agent onboarding and Dot
setup.
- Include it in the server onboarding document, pairing response, event
instructions, and capability response.
- Clarify the tool descriptions on both Dot bridge paths.
- Include the same guidance in each Dot Runner assignment without adding
a shared-package dependency to the standalone Runner.
- Document native tool use and the scope of test restrictions.

## Verification

- The 49 relevant onboarding, Dot invitation, and Runner context tests
passed. The final UI run passed 29 tests. The updated plain-text
renderer run passed all 4 tests.
- Full workspace typecheck, full workspace build, and design token gates
passed. All current-head CI gates passed, including full tests, Runner
verification, and browser E2E. Greptile is 5/5 on the exact final
commit, and the one review finding is resolved.
- The real Dot received the standing correction and confirmed that it
will use its relevant tools and connections, return results through
Paperclip, and stop carrying the test restriction forward.
- Extended the existing plain-text renderer test to check native Slack
access, qualification-test scope, and the Paperclip denial boundary.
This covers agents that receive only the onboarding.txt URL.
- The full Vitest suite passed in CI. The earlier local Cloud
qualification run encountered failures in unchanged suites; this
follow-up uses focused local tests for the instruction changes.

## Risks

This changes instructions, not access checks. Native tools retain their
own permissions and approval requirements. Paperclip operations remain
scoped to the authorized company, agent, and task. Agents must not use
another connection or identity to bypass a denial. There is no database
migration or new permission grant.

## Model Used

OpenAI GPT-6 through Codex. Used reasoning, repository tools, and
browser control. The runtime does not expose a more specific model ID or
context window size.
