v0.6.2

Added

• Notify the server console and players when the crash-recovery journal degrades,
  including when a session may no longer be recoverable.

Changed

• Reduce CPU overhead of persistent Linux allocation-rate metrics while preserving
  allocation profiler and unload behavior. Single-writer counters reduced observer
  cost by 7.3-13.3 ns/op across seven single-thread benchmark workloads, with
  unchanged reported counters and one-thread hook coverage.

Fixed

• Exclude resolved Linux allocation-hook callback frames from execution profiles.
• Keep recovery journal size accounting accurate when retained segments disappear
  or cannot be statted, and stop journal growth after persistent metadata snapshot
  failure or stalled pruning while profiling continues.
• Prevent repeated startup replay of the same journal generation after cleanup
  fails, and retain the first degradation cause and notices across session finalization.
• Preserve world gauge counts while the level is unavailable and retry failed tile
  reconciliation after a five-second backoff.
