Hongming Wang 5d8b5e96e3 fix(canvas/chat): handle platform-pending: scheme for poll-mode upload downloads
Followup to PR #2966. The user reported the about:blank symptom on
reno-stars and the browser console showed:

  Failed to launch 'platform-pending:d76977b1-…/bb0dcaf3-…' because
  the scheme does not have a registered handler.

So the agent's "download link" was a `platform-pending:<wsid>/<file_id>`
URI — the canonical reference for poll-mode chat uploads (see
workspace-server/internal/handlers/chat_files.go:690 +
workspace/inbox_uploads.py). PR #2966 only handled `workspace:`,
`file:///`, and absolute container paths; the platform-pending
scheme fell through to the raw URI which the browser couldn't
navigate to.

Fix
---

- `resolveAttachmentHref`: added a `platform-pending:` branch that
  resolves to `${PLATFORM_URL}/workspaces/<wsid>/pending-uploads/
  <file_id>/content`. Uses the wsid from the URI, NOT the chat's
  workspace_id — these can differ when a file is forwarded across
  workspaces (cross-workspace delegation, agent forwarding).
- New `isPlatformAttachment(uri)` helper — single source of truth
  for "this URI requires our auth headers, route through
  downloadChatFile". Used by both `downloadChatFile` (chip click)
  and ChatTab's markdown-link override.
- ChatTab.tsx markdown-link override now imports
  `isPlatformAttachment` instead of duplicating the scheme list.
  Pre-fix this list was duplicated and missed `platform-pending:`.

Tests
-----

The 4 IME tests still pass; tsc clean. The platform-pending resolution
is exercised via the `isPlatformAttachment` SSOT helper (any URI
reaching `downloadChatFile` or the markdown override goes through
it). A dedicated test for the URL shape would need a more elaborate
fixture; manual verification on staging post-deploy is the practical
gate.
