* fix(filer.sync.verify): sort listings client-side before merge
The merge walks both filers' directory listings in lockstep and needs
them in the same byte order. A filer before 4.32 with a locale SQL
collation lists case-insensitively while a 4.32+ peer lists byte-ordered,
so comparing two such clusters returns the same names in a different
order and the merge desyncs into spurious MISSING / ONLY_IN_B.
Buffer and sort each directory client-side so both sides agree on order
regardless of filer version or store backend. Trades the streaming
source's O(buffer) memory for O(directory) per side, fine for a one-shot
verify CLI; both sides still load concurrently.

* fix(filer.sync.verify): surface listing errors before merging
A listing that fails mid-stream leaves a partial, unsorted buffer. Now
that both sides are fully buffered anyway, check each side's error right
after the loads finish and before the merge, so partial entries can't
emit spurious MISSING / ONLY_IN_B before the error aborts the run.
