Record segment names on replay events

[sentry-junior]

Add segment names observed during span streaming to each Android replay event so Flutter can correlate named segments with usable replays.

• Add segment_names (List<String>) to SentryReplayEvent, including JSON serialization/deserialization, equality, API dumps, and tests.
• Extend ReplayController / replay integration with a segment-details registration API accepting a trace ID and segment name.
• Deduplicate and cap both collections at 100 values per replay segment, then clear them together after segment creation.
• Populate trace_ids and segment_names on the same replay event.
• Add capture-strategy and serialization tests covering deduplication, limits, disabled replay, and segment rollover.
