Function try_parse 

pub fn try_parse(
    entry: &LogEntry,
    timestamp: Option<DateTime<Utc>>,
) -> Option<GameEvent>

Attempts to parse a LogEntry as a connection-error event.

Dispatches on entry.header:

• EntryHeader::UnityCrossThreadLogger — inspect the body for one of the four JSON-bearing error markers. Bare-marker bodies (no JSON payload) return None.
• EntryHeader::ConnectionManager — parse the body for Reconnect result : <value> or Reconnect <outcome> plain-text markers.
• EntryHeader::Matchmaking — parse the body for Matchmaking: GRE connection lost.
• Any other header — return None.

The timestamp is None when the log entry header did not contain a parseable timestamp. It is passed through to EventMetadata so downstream consumers can distinguish real vs missing timestamps.
