Background

CLI v2.1.76 added a PostCompact hook that fires after context compaction completes.

Why It Matters for Hikari Desktop

Hikari Desktop tracks context window usage and has a disable_1m_context toggle. However, the UI currently has no signal that compaction has occurred mid-session. When compaction runs silently:

  • Token/cost counters in the stats panel may appear to reset unexpectedly
  • The character may stay in an active state during the compaction pause
  • Users are unaware that their context has been compacted, which can be surprising

Handling PostCompact allows us to:

  1. Show a brief toast or status-bar notice ("Context compacted")
  2. Refresh the context window stats display
  3. Potentially show a distinct character animation for compaction (or briefly use the success state)

Acceptance Criteria

  • PostCompact event parsed in wsl_bridge.rs and emitted to the frontend
  • Toast/notice displayed when compaction completes
  • Stats display refreshed after compaction
  • Tests for the new event type
