fix(RC-4): narrow FetchNotIndexedError swallow in prebuild handler (Phase 3)

- Add specific except FetchNotIndexedError: raise guard before the broad except Exception in process_fetch_mpack_prebuild_job. FetchNotIndexedError now propagates to the worker so fail_job records it as a retryable failure instead of silently returning tips_built=0. - Add MWP4_10 test: confirms FetchNotIndexedError propagates after the fix. - MWP4_02 (Phase 0 RED test) also now green — it asserts the exception propagates, matching Phase 3 behavior. - All 10 MWP4 tests green; 32 adjacent tests green, zero regressions. - Tick Phase 3 checkboxes in docs/issues/mwp-4-prebuild-after-index.md.
