Last round of targeted wins:
- upload-manager progress callback was allocating a fresh
{ jobId, speedKbs, bytesUploaded } object on every fs stream chunk
(hundreds of times per second per active job). Now a single entry
is created at job start and mutated in place — zero allocations
on the steady-state progress tick.
- upload-manager stats timer's two separate activeJobs.values()
scans (globalSpeedKbs + inProgressBytes) merged into one pass.
- clouddrop-upload.js reuses a single Buffer.allocUnsafe(chunkSize)
across all chunks, taking subarray() only for the tail chunk.
A 1 GB upload no longer allocates 64× 16 MB = 1 GB of short-lived
buffers — real GC relief during many-file batches.
- _resolveUploadLogTarget is now cached; the fallback ladder runs
once per session (or when the user changes the log path / daily-log
date rolls), not on every 500ms flush.
- renderRecentUploadsPanel skips updateRecentSortHeaders on the
append-only fast path — sort state hasn't changed, headers don't
need recomputing.
