Near matching exists to reconcile two sources describing one event under
different titles. Within one source it has no such job: the page has already
told us these are two rows, the parser has already dropped repeats of the same
id, and fusing them overrules a distinction the publisher made on purpose.
The loose 0.80 threshold that makes the rule useful across sources makes it
actively wrong within one. Umamusume's banner list runs "3 Star Guaranteed 1.5
Anniversary Scout (Character)" and "(Support)" concurrently — titles differing
by a single parenthetical, starting the same day — and fusing them dropped a
live banner off the calendar with nothing anywhere reporting it. A silent drop
is the failure this codebase ranks as the dangerous one.
Same-id fusion is untouched, so nothing duplicates.

First non-Game8 parser, and the first source that states region-scoped ends:
wiki.gg emits ISO timestamps with one timer per server region, so Endfield
events now carry exact times and separate Asia / Americas-Europe ends. That
gap is up to 13 hours, which is what regionEnds was built for.
Two sources for one game also exercised merge for real. It caught both
overlaps — including "Bedazzling Dawnstar" against Game8's "Bedazzling
Dawnstar Sign-In" — and flagged that the two disagree on the end date by 70
hours rather than averaging them into a date neither states.
Matching an appended qualifier needed a prefix test, not a subset test: a
subset would also fuse "Gold Clash" with "Gold Rush Clash Royale".
Also fixes build-feed picking fixtures by game rather than by source, which
handed the wiki.gg page to the Game8 parser once Endfield had two.

Collapses the same event seen by two sources, matching on ID or on title
similarity plus start-date proximity. Proximity is the real guard against
false positives, since a rerun reuses its name months later.
Agreement from an independent source raises confidence; the same row seen
twice in one document does not. Disagreement on an end date is recorded as
a conflict for the review gate rather than averaged — splitting the
difference would publish a date neither source asserts.
