v0.128.0: chunked browser .fab upload on /import (tunnel-proof)

Browse Source 
Cloudflare edge caps request bodies (~100 MB, probed live: 120 MiB -> edge 413,
80 MiB -> origin), so the client slices the file into 64 MiB strictly-sequential
chunks; the server streams each to a .part file in the default drive's exports
dir and finalize renames atomically. Scan/validate/import pipeline untouched.
upload/{init,chunk,finalize,abort} inside ServeExportAPI (inherits auth+CSRF);
single-flight; offset==received or 409+echo; free-space gate; collision ->
lowest-free "name (N).fab"; startup GC of *.part-*; 15-min idle abort.
appexport.DiskFree exported (seam web.uploadDiskFree). Scenarios A-F tested,
red-proofs run (traversal / out-of-order / overwrite).
