`Fbe::Iterate#over` loses `repo` and item context when block raises an exception

[morphqdd]

In iterate.rb, yield(repo, nxt) is called without a rescue block:

before[repo] =
  if nxt.nil?
    # ...
  else
    @loog.debug("Next is ##{nxt}, starting from it")
    yield(repo, nxt)   # raises StandardError → no context logged
  end

The existing rescue at the end of over catches only Fbe::OffQuota. Any other exception propagates up with no information about which repository (repo) or which item (nxt) caused the failure.

In production this makes debugging iteration failures extremely difficult — the stacktrace shows the exception type but not the repository or fact being processed at the time of the crash.

What should happen: the yield call should preserve context before re-raising, e.g.:

begin
  yield(repo, nxt)
rescue => e
  raise "#{e.class} in #{repo} at #{nxt}: #{e.message}"
end

I'd like to work on this. Will preserve the repo and nxt context by wrapping the yield call in iterate.rb#over with a begin/rescue that re-raises with a contextual message.

Submitted #455 — preserves the repo and nxt context by wrapping the yield(repo, nxt) call in Fbe::Iterate#over with a begin/rescue. Fbe::OffQuota is re-raised unchanged so the existing handler still triggers; any other StandardError is re-raised with the same class but a contextual message ("Failure in repository #<repo> at #<nxt>: ..."). All 10 CI checks are green.
