Nic Boet 4b098fb760 perf: replace O(n) linear frame seeks with O(log n) binary search 
Replace two linear scans in event playback seeking:

- seek(): O(n) walk from frame 0 replaced with std::lower_bound on
  timestamp. Falls back to last frame if target is past end.

- processCommand(CMD_SEEK): O(n) estimate-then-walk replaced with
  std::upper_bound on offset, then step back one. Handles edge cases
  where offset lands before first frame or past last frame.

For a 10-minute event at 30fps (~18,000 frames), worst case drops
from 18,000 comparisons to ~14 (log2).
