Gregor LohausandClaude Opus 4.8 e99a6ee33e split snapshot profiler bucket into update vs marshal 
The snapshot bucket lumped ghostty's native dirty-state update together with
the Java-side cell marshaling. Time them separately to see which half of the
~7ms/frame snapshot cost (now the dominant frame cost after the detectShift
hoist) is the real target.

Gregor LohausandClaude Opus 4.8 4923ea5527 hoist row hash out of detectShift delta scan 
rowFingerprint(row) is invariant across the delta loop but was recomputed for
every candidate delta, making shift detection O(rows^2 x cols) on large changes
(full-screen scroll). Precompute each changed row's hash once, dropping it to
O(rows x cols). Profiling showed fingerprint hashing at ~74% of frame time under
heavy scroll, dominated by this loop.

Gregor LohausandClaude Opus 4.8 1f7394d75a add opt-in render profiler instrumentation 
Gated behind -Djprototerm.profile=true (or JPROTOTERM_PROFILE=1), accumulates
per-frame nanos into snapshot/fingerprint/draw/frame-total buckets and dumps
to stderr every N renders. Splits the three suspected render costs: native
snapshot marshaling, fingerprint hashing, and canvas draw recording.
