[PATCH] doc: design_www: document solver endpoint

[Eric Wong <e@yhbt.net>]

The blob regeneration (solving) part has been stable and
performant for over a year with no problems, even with web
crawlers constantly hitting it without needing rate limits.

All the other stuff is open to bikeshedding (as long as
my crappy hardware supports it :P)
