Add native binary export (win/linux/mac players) to the pipeline

TIC-80's export win/linux/mac produces self-contained players with
the cart baked in; the templates are downloaded from tic80.com at
export time. The zips follow the <name>-<version>-<slug>.zip droparea
convention so the API registers them as release assets automatically.
Also switch the tic80pro image reference to the canonical registry
host.
