Listing files with a tag filter now logs each referenced tag to activity.tag_uses, flagging it included (positive) or excluded (negated under an odd number of NOTs); the untagged pseudo-token is skipped. The filter AST is reused to determine polarity, so grouped negations like !(A|B) mark both tags excluded. Recording happens only when a filter is first applied — not on cursor pagination or an anchored return — so one browse counts once. The write is best-effort and never fails the listing.
