Per sub-project-2 plan Task 4 / spec §5.1. derive_tags(Probe) -> Tags with the
attached_pic cover-art guard so an art-bearing audio file stays mode=audio.
Duration falls back to the longest stream when format.duration is absent, and
rounds half-up so 12.5s -> 13s (Python's round() would give 12 via banker's
rounding) to match the spec's stated behavior.

Per sub-project-2 plan Task 2 / spec §3. Purely additive to hef.catalog;
no existing symbol changes. validate_catalog runs per-record validate() then
asserts id uniqueness; index_by_id gives by-id lookup the player also wants.
