Godspeed Code 0.5.10

Added

• Usage in the session card. The thread details card shows how much is left in each limit
  window of the chat's account (5-hour first, then weekly) and how full the context window is,
  with reset times on hover. It reuses the usage data the composer gauge already loads.
• fx as a provider. fx acp runs through the ACP driver like the other agents (from Zeron).

Changed

• Much less background work while you're away. With 10 chats open in their own worktrees,
  Godspeed now starts about 25 git processes in 10 idle minutes instead of 375. Diffs refresh
  when you come back, when a turn ends or when files change, with a safety check every 15 minutes
  only while you're active; build output in target/ and node_modules/ no longer triggers
  refreshes. The PR watch backs off properly when you're away, and build-slot checks stop when
  nothing can build.
• A calmer Dock buddy. The speedster falls asleep on a still frame after 45 seconds of quiet
  instead of animating forever. While agents work it keeps running, capped at 4 fps on battery,
  in Low Power Mode or when every window is hidden. A waiting alert settles after a minute.
• Lighter redraws. A running zoomie animates only its own row instead of redrawing the whole
  window, and Mission Control repaints only the card that moves.
• Quieter launch. The empty-chat check at launch is cheaper, agent update checks wait 90
  seconds and are reused for 6 hours, and usage meters don't refresh while no window is visible.

Fixed

• One slow agent CLI no longer stalls every other agent lookup while its version is checked, and a
  failed version check is retried instead of cached until restart (from Zeron).
• Direct device links over Tailscale (MTU 1280) now carry data: WebRTC packets may fragment (from Zeron).
