improvement(chat): unify message styling and source previews

[waleedlatif1]

Summary

• Use main’s Inter typography consistently across organization, workspace and workflow chat, including composers and source previews. Share inline references, file tags, choice controls and activity spacing.
• Use existing tokens for inline code and links, center favicons, and preserve mixed formatting in nested lists. Keep full table cells in native horizontal scrollers with the canonical edge fade.
• Add one source preview for links and citations with intent-loaded, cached public metadata and bounded Open Graph thumbnails. Private connector sources retain their supplied metadata. Limit thumbnail concurrency, retry transient image failures on later intent, and propagate cancellation through guarded DNS validation.

Type of Change

• Improvement

Testing

The broad regression pass covered 3,121 passing tests. The latest changes passed 2,922 chat, composer, editor, preview, stream and security tests; one existing parser stress test timed out under parallel load and passed on an isolated rerun. Type-check and lint-check passed across all workspaces; all 49 audits, block registry, generated artifacts and docs manifest checks passed. Compared production components with main in light/dark themes and narrow layouts, including table edge fades, keyboard scrolling, mixed formatting and source previews. Completed the cleanup/design review.
