Subject: [PATCH] Auto-pin owner via area-entered + level event; filter
 party-member level events

Tracks the local player by listening for `: You have entered <area>.` and
the next level event in that window, then ignores subsequent `: <name>
(<class>) is now level <n>` lines for any other character. Party joins
inside an unpinned area window mark the window INVALIDATED so we don't
mis-attribute a party member's level event to the local player. Setting
`POE2_CHARACTER_NAME` short-circuits the state machine to PINNED on first
area entry.
