fix(search): tag-aware snippet truncation prevents cutting inside <mark> pairs (GIT-5)

The old truncation counted <mark></mark> HTML tags (~13 chars per keyword)
as visible characters, causing over-aggressive truncation. When a cut
landed inside a tag pair, render_snippet would render highlighted text
as muted gray instead of bold yellow.

New truncate_snippet() walks through markup counting only visible
characters, respects tag boundaries, and always closes an open <mark>
before appending ellipsis. Includes 6 unit tests.
