Slice 3 of search-core. Search results now show WHY they matched: a ts_headline
body fragment with matched terms highlighted. The API returns U+E000/U+E001
sentinels around matches (NOT HTML); the client tokenises them into escaped
<mark> React elements, so untrusted email content can never inject markup (no
dangerouslySetInnerHTML). Subtle accent tint. Only when there's a free-text query
(browse unchanged); projection branched (no DB function in a ternary) for
unambiguous EF translation.
Verified: build + all 40 tests; ts_headline output shape in raw Postgres; and the
ranked+headline EF query proven to translate + execute against a live Postgres via
a throwaway test (removed).
