The web version of Gmail sometimes tells me a message wasn't sent to
spam because of my filter settings:
However, after I download that message via IMAP and look at the
headers, I see no such indication ("show original" also shows no such
indication).
Is this information lost if I don't view the message on the web?
Can I make gmail add a "X-GMAIL-FILTERED: Spam to Inbox" or something
header?

This is a GMail web feature and would not be included in the normal HTML of an email. The information is not really lost, but more a less not an included feature of using IMAP or POP access.
