Burrow 0.7.1

Burrow 0.7.1

A stability release. The 0.7.0 redesign shipped with a handful of freezes — and
one crash — that telemetry caught in the first day. This clears every app-hang
and the crash reported since launch, plus two long-standing freezes that predate
the redesign. No new features; just the redesign, holding still.

Freezes & a crash, fixed

• History view no longer locks up. Opening a wide time range (up to 90 days)
  could freeze the app for a couple of seconds while the bar charts laid out —
  the worst regression from the redesign. Charts now down-sample cleanly and stay
  responsive. (#57)
• Faster launch, no hang. Startup no longer blocks the main thread while it
  looks for the mo engine — the lookup moved off-thread. (This one predates
  0.7.0 and has been one of the most common freezes in the wild.) (#72)
• Fixed a crash opening the menu-bar popover. The mini charts in the popover
  and the Status tiles could segfault during a transition; they now draw as a
  single shape, the same way the History charts do. (#75)
• Smooth typing in Uninstall & Purge. Keystrokes sent to the interactive mo
  sessions no longer risk parking the UI when the engine's output backs up. (#73)
• Steadier process list. The per-row Quit / Force-Kill menu in Status no
  longer rebuilds its labels on every two-second refresh. (#74)

Charts & metrics

• GPU history bars draw again on Apple Silicon (they'd been reading as a flat
  zero).

Under the hood

• One refresh pump for live metrics. The HUD, Status, and Activity panels now
  share a single refresh source instead of each spinning its own timer — less
  churn and fewer redundant mo calls. (#53)
• One audited engine path. Every mo call — snapshot, streaming, the
  interactive PTY sessions, and privileged operations — now flows through a single
  facade, which makes future privileged-operation work safer to build on. (#48)
