updateEntry's .map() always returned a new array even when no entry matched,
causing unnecessary state changes. During note creation, addEntry uses
startTransition (deferred) while markContentPending calls updateEntry
synchronously — the entry doesn't exist yet, so the no-op .map() produced a
new reference that cascaded into "Maximum update depth exceeded" (which
surfaced as React error #185 in the production WKWebView build).
The fix makes updateEntry bail out (return prev) when no entry was changed,
preventing the spurious state update. Also removes the defensive try-catch
from the previous fix attempt and cleans up an unnecessary setToastMessage
dependency.

Add FolderTree component tests (render, expand, collapse, select,
highlight) and folder filtering tests in noteListHelpers (path
matching, sibling exclusion, archive/trash filtering).
ADR-0033 documents the decision to scan all subdirectories and
expose folder tree navigation, superseding ADR-0006's scanning
constraint.
