Daneel f42e799991 patches: fix Blocker #2 - remove ensureTextCache from notification path ...

BUF_MODIFF was needed for fold/unfold correctness (org-mode), but
ensureTextCache was called from postAccessibilityNotificationsForFrame:
on every cursor move, causing O(buffer-size) rebuild on every font-lock
pass.

Fix: remove [self ensureTextCache] from the granularity-detection branch
of the notification path.  The granularity detection now uses cachedText
directly, falling back to granularity_unknown when absent (safe: VoiceOver
makes its own determination).  ensureTextCache is called exclusively from
AX getters (human interaction speed).  Font-lock passes no longer trigger
any cache rebuild.

The BUF_MODIFF validity in ensureTextCache is retained (correct for
fold/unfold). Comment updated to accurately describe the calling pattern.

All 9 patches apply cleanly on fresh base (git apply verified).
