This PR is part of the original ai-chat stack which has been superseded by a restructured version. Closing in favour of the new stack:

• feat(apollo-vertex): ai-chat shell — branding, empty state, thinking indicator [1/5] #628 — Shell, empty state, thinking indicator [1/5]
• feat(apollo-vertex): ai-chat code blocks — syntax-highlighted fenced code with copy [2/5] #629 — Syntax-highlighted code blocks [2/5]
• feat(apollo-vertex): ai-chat message actions — copy, feedback, edit, regenerate [3/5] #630 — Message actions: copy, feedback, edit, regenerate [3/5]
• feat(apollo-vertex): ai-chat file attachments — upload, paste images, preview [4/5] #631 — File attachments: upload, paste images, preview [4/5]
• feat(apollo-vertex): ai-chat text selection — Ask AI floating pill + quote chip [5/5] #632 — Text selection: Ask AI floating pill + quote chip [5/5]

The new stack is reorganised by user-facing feature rather than component type, includes all the same functionality plus attachments and text selection, and has a clean single-commit-per-PR history.
