Phase 5 of the UX overhaul. Migrates search result display from raw
console styling to the centralized Theme system with semantic methods,
improving visual consistency and readability.
Search result changes:
- Type badges now use semantic styles (issue_ref, mr_ref) with
fixed-width alignment for clean columnar layout
- Snippet rendering uses Theme::highlight() for matched terms and
Theme::muted() for surrounding context, replacing bold+underline
- Metadata line uses Theme::username() for authors and per-part
styling with middle-dot separators instead of a single dim line
- Result numbering uses muted style with right-aligned width
- Consistent 8-space indent for metadata, snippets, and explain lines
- Header line uses muted style for search mode instead of dim+parens
- Trailing blank line moved after the result loop instead of per-result
