v0.0.8 — retry upload

Same package as 0.0.7, with a clean version number.

Why this exists

The 0.0.7 upload to AMO stopped at 85% (139KB of 163KB) with "There was a problem
contacting the server". The validator never ran — that message is a transport failure, not a
verdict on the package. Nothing was wrong with the zip; it lints at 0 errors / 0 warnings /
0 notices here, and the 0.0.4 upload passed validation cleanly.

AMO will not accept a version number it has already seen, even from a failed attempt, so this
is 0.0.8 rather than a retry. The code is identical apart from the version string.

Which file goes where

file	where it goes
chevalet_note-0.0.8.zip	the Upload Version page — this page takes one file
source-0.0.8.zip	a later step, after Continue, when AMO asks "Do you need to submit source code?" → Yes

The source archive is not optional for us: the build is minified, and AMO requires the original
source whenever the shipped code is. SOURCE.md inside the archive is written for the reviewer.

If the upload keeps stalling

It is a 163KB file, so a stall at 85% is a connection problem rather than a size problem. Try
again first; it usually goes through on a second attempt. If it does not, docs/PUBLISHING.md
covers uploading through the AMO API instead, which is a single command and does not depend on
a browser session staying up.
