TVmaze: drop trailing slash from base URL (was producing //shows/), send
season/number as plain ints (TVmaze rejects zero-padding), check HTTP
status before decoding so 404 bodies stop being decoded as episodes, and
fetch /shows/{id} separately for show name + IMDb mapping —
episodebynumber does not honor embed=show despite what the docs imply.
OMDb: check HTTP status, and include a body snippet when Response is
non-True with an empty Error field so rate-limit and HTML failure modes
are diagnosable.
Both: assert that the fields we actually depend on come back non-empty
after decode. Catches silent field rename/removal without making us
fragile to TVmaze adding new optional fields.
main.processFile: split the nometadata fallback by branch. Series uses
Collection (legitimate shows can have no IMDb mapping); movies keep the
IMDBID/Title check.
