DottaandPaperclip e912f0df53 fix(ui): open text attachments in task tabs (#14297)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - Agent work often ends with a Markdown or plain-text file.
> - Task attachments currently open outside the task panel.
> - Users need to inspect those files while keeping the task
conversation in view.
> - This pull request opens text attachments in task tabs and adds
rendered, raw, and download controls.
> - The same controls work in the mobile task drawer.

## Linked Issues or Issue Description

**What happened?**
Opening a text attachment did not put its content in a task tab.
Markdown files had no in-task rendered/raw toggle.

**Expected behavior**
Open Markdown and text attachments in one reusable task tab. Show
Markdown as rendered content or raw text. Download the original file.

**Steps to reproduce**
1. Upload a Markdown file and a plain-text file to a task comment.
2. Open each attachment from the task conversation or artifact list.
3. Switch Markdown between Rendered and Raw. Download both files.
4. Repeat at a mobile viewport width.

Related work: #14193 controls artifact tab arrival. This change adds
text attachment content tabs.

## What Changed

- Route text attachment opens from conversation and artifact cards into
task tabs.
- Add a text attachment panel with accessible Rendered, Raw, and
Download controls.
- Preserve ordinary links for other file types.
- Support the selected attachment in the mobile drawer.
- Keep text-tab actions on the current rich artifact cards, including
CSV previews.
- Render attachment image references and diagram source without loading
media URLs.
- Add browser regression tests, component tests, Storybook examples, and
usage documentation.

## Verification

- Full workspace typecheck, production build, Storybook build, and UI
token gates pass locally.
- All 6,960 UI tests pass. The additional media regression passes
against the real Markdown renderer and fails before the fix. CSV
coverage verifies direct downloads and text tabs after preview.
- Both desktop and mobile browser cases pass locally. They check
rendered/raw Markdown, literal plain text, reusable tabs, review
controls, and exact original download bytes. The local fixture used a
separate database port because an existing socket occupied the default
range.
- The full CI test matrix passes on
`82be5efbef26927b237a031725bb3d7fa79f637f`. The duplicate local `pnpm
test:run` was stopped after this CI result; it did not complete locally.
- Greptile is 5/5 on the final commit. All review threads are resolved,
and the security scan passes.
- All 54 final-head checks pass, including the canary dry run. The two
optional Storybook jobs are skipped.

## Risks

- Text attachment links now open in the task panel. Other content types
keep their existing link behavior.
- File display still depends on the existing authenticated attachment
route. There are no API or database changes.
- Raw text is displayed as text, including strings that look like HTML.
Rendered Markdown keeps media references inert.

## Model Used

OpenAI Codex, based on GPT-6, with code execution, browser testing, and
subagent tool use. The runtime does not expose an exact serving model
variant or context-window size. Recovered earlier implementation changes
were reviewed and tested; their exact model metadata is unavailable.
