Stop the 412/416 partial-reget loop on continue/update (#206)

On resume, the Range request is rebuilt by back_add from a temp-ref keyed on
(adr,fil) that records the partial download's real save name. A 412/416
("Range Not Satisfiable") means that partial is stale and the whole file
must be re-fetched. The handler only removed heap->sav, so when the resume
pass recomputed a save name different from the temp-ref's (the default
delayed-type machinery renames freely), the partial was never cleared:
back_add re-sent the same Range, earned the same 416, and the link was
re-recorded forever, growing the scan counter without bound.

Clear the whole partial wherever it lives -- the temp-ref and the file it
points at, plus heap->sav -- so the re-record falls through to a plain full
GET. Re-get only when there was a partial to discard and both Range triggers
(the ref and the on-disk file) are actually gone; once they are, a fresh 416
with nothing left to drop means the whole-file GET itself failed, so the link
gives up cleanly instead of re-queueing. A failed removal (read-only or full
cache) also gives up rather than looping, since back_add would otherwise
re-Range the surviving ref; url_savename_refname_remove now reports the
removal result so the handler can tell. (The request's range_used flag would
be the natural one-shot signal, but it does not survive the delayed-type
two-pass, so we key off the partial instead.)

tests/20_local-resume-loop.test drives it offline: pass 1 is interrupted
(SIGTERM, so the exit handler finalizes the cache and the temp-ref) to leave
a partial, then pass 2 --continue gets 416 on every resume request. A
portable watchdog kills pass 2 if it loops; the test asserts it terminates
and attempts exactly one whole-file re-get (2 <= requests <= 8). It fails on
the pre-fix handler (loops) and on a re-get that silently drops the link.
