snippetOf() stripped only tag delimiters with a single regex on every
body, HTML or not: <style>/<script> text leaked into HTML snippets,
entities stayed encoded, and plain-text bodies had literal <...> text
eaten as if it were markup.
Replace it with Snippet.of(body, isHtml), which finally consults the
isHtml flag both call sites already had: HTML bodies go through
HtmlToText (script/style content dropped, tags stripped, entities
decoded), plain text gets no markup handling at all; both paths keep
the whitespace collapsing and the 140-char cap. HtmlToText's entity
decoding is now a single-pass decoder that also handles decimal/hex
numeric character references and never re-decodes produced characters.
Snippets are persisted when a body is first fetched and never
re-derived, so existing rows would keep their broken snippets forever;
a data-only v13->v14 migration re-derives every cached row's snippet
with the corrected logic (schema unchanged relative to v13, exported
14.json committed).
