Adds three COORDS_*_REGEX constants (at-clause, bracketed, parenthesised)
plus COORDS_REPLACEMENT, wires them into redact(), and covers all three
contexts with 8 new tests including a critical negative test asserting
DebugLog-server.txt server-metadata triples are not redacted.
Also updates two Task 3 player-name tests whose expected strings now
include the coords redaction that the wired pass applies.

Adds three lexical-context regexes (after-SteamID, ChatMessage author,
Combat/Safety pvp subsystem) and wires the player-name branch in redact().
Includes six PHPUnit tests covering all three contexts plus the toggle-off
and no-anchor-no-touch cases.
