## Why
Path-like link labels were collapsed into their destinations, discarding the author's label text and formatting.
## What changed
Preserve nonblank local link labels alongside the formatted destination as `label (target)`, including in tables. Empty or whitespace-only labels show only the destination. Keep destination formatting and fall back to the original destination when a local file URL cannot be parsed.
Render file citations without a label so they continue to display only the formatted destination.
## Testing
Update rendering and transcript-copy tests and snapshots to cover preserved path labels, styled labels, empty labels, malformed file URLs, tables, and Markdown escaping.

## Why
Follow-up directives contain display labels and prompt attributes. Show the labels without exposing directive syntax or prompt text in rendered responses and streaming previews.
## What changed
- Render `:codex-followup[label]{prompt="..."}` as its label, preserving inline Markdown styling and source offsets.
- Replace recognized follow-up directives with their labels when copying whole responses, while retaining the original source.
- Withhold unfinished directives in rich streaming previews and avoid cropping into prompt attributes when the preview window advances.
- Preserve literal code, escaped directives, and malformed source when rendering completed messages or copying responses.
## Testing
Add regression coverage for label formatting, nested brackets and backticks, literal and malformed directives, whole-response copying, and streaming holdback across long prompts and preview window boundaries.
