feat(daemon): route bulk-scale rebuild through daemon-owned generation build

 | `daemon_parse_stage_split` | `daemon.raw_materialization.parse_stage_split` | Opt-in (polylogue-m6tp phase (a), default off): pre-parse raw-materialization census candidates in a bounded daemon-owned thread pool before the writer hold, instead of parsing inside the writer-held pass. |
