Resolves observation #3 from the final code review. The integration
tests previously asserted Steam-ID elimination, structural
preservation, and idempotence but did not directly verify that
synthetic player names collapse to <player> after redaction.
Adds testFixturePlayerNamesCollapseInCoveredContexts, parameterised
over the five fixtures (chat, cmd, item, map, user) where every
synthetic name appears exclusively in a context the redactor
recognises (ChatMessage author or Steam-ID-followed-by-quoted-name).
The data provider docblock explicitly enumerates which fixtures are
excluded and why — admin and client-action/perk because names appear
in unanchored or bracket-only contexts; pvp because the victim name
after `hit` is a v1 limitation; burd-journals/debug-server because no
synthetic player names are present.
Test count: 255 -> 260 (5 new effective cases from data-provider).
