Zainan Victor Zhou 778fd1898e fix(slack): surface attachment access diagnostics
Translate Slack attachment failures into actionable user-facing notices
instead of generic download errors. When a scope/auth/permission issue
breaks attachment processing, the user sees:

  [Slack attachment notice]
  - Slack attachment access failed for photo.jpg. Missing scope:
    files:read. Update the Slack app scopes/settings and reinstall
    the app to the workspace.

Two helpers do the translation:

  _describe_slack_api_error — handles SlackApiError responses
    (missing_scope, invalid_auth, file_not_found, access_denied, etc.)

  _describe_slack_download_failure — handles httpx.HTTPStatusError
    (401/403/404) and Slack-returns-HTML-sign-in fallbacks

Wired into three existing call sites:
 - the Slack Connect files.info path (PR #11111) so scope errors
   surface instead of being logged as generic "files.info failed"
 - the image, audio, and document download paths so 401/403 and
   HTML-body responses translate into actionable notices

Adjustment from original PR: dropped _probe_slack_file_access_issue,
the proactive pre-download files.info probe. It added one extra
Slack API call per attachment even on healthy ones, and overlapped
with the existing files.info call from PR #11111. The post-failure
translation path covers the same user-facing diagnostic value
without the per-message tax.

Also documents files:read scope more prominently in the Slack setup
guide and troubleshooting table.

Website

This website is built using Docusaurus, a modern static website generator.

Installation

yarn

Local Development

yarn start

This command starts a local development server and opens up a browser window. Most changes are reflected live without having to restart the server.

Build

yarn build

This command generates static content into the build directory and can be served using any static contents hosting service.

Deployment

Using SSH:

USE_SSH=true yarn deploy

Not using SSH:

GIT_USER=<Your GitHub username> yarn deploy

If you are using GitHub pages for hosting, this command is a convenient way to build the website and push to the gh-pages branch.

Diagram Linting

CI runs ascii-guard to lint docs for ASCII box diagrams. Use Mermaid (````mermaid`) or plain lists/tables instead of ASCII boxes to avoid CI failures.
