Add authenticated uploads and rename fossmark to fossbench

Uploads can now be attributed to a fossbench.net profile: set
FOSSBENCH_TOKEN and the client sends it as a Bearer token, which the
server auto-approves and links to the account. Anonymous, pending-review
upload stays the default when no token is set. New --upload/--noupload
flags skip the interactive prompt for scripted runs, and the client
reports HTTP 401/422 distinctly from other failures. The token is never
printed or logged.

Also renames the project and its internal identifiers (FM_/fm_ macros
and symbols, source filenames, binary output names) from fossmark to
fossbench, matching the actual product name. The "fossmark_version"
field in the upload payload is left as-is, since it's the server API's
fixed contract field, not this client's own name.
