docs: add ADRs 0024–0031 for SIP-TP launcher stack
ADR-0024 (SIP-level TP launcher): rank = SIP abstraction, engine-routed
install, mp.spawn parity, epoch barrier, ShardSpec structural coords.
ADR-0025 (IPCQ direction addressing): address-based matching for meta
arrival and credit return; fixes 2-rank bidirectional ring deadlock.
ADR-0026 (DPPolicy intra-device only): remove sip/num_sips fields;
ShardSpec uses structural (sip, cube, pe); pe_index property removed.
ADR-0027 (Megatron-style TP API): ColumnParallelLinear / RowParallelLinear
on top of ADR-0024 launcher. Backlog until 0024/0025/0026 land.
ADR-0028 (DTensor support): stub / future work.
ADR-0029 (Hierarchical all-reduce): 3-level reduce using all_pes mapper
and multi_pe_sip_local validator from ADR-0024. Backlog.
ADR-0030 (IPCQ PhysAddr integration): blocked on ADR-0031.
ADR-0031 (PhysAddr PE-resource extension): stub; local_offset range-based
partition approach; specific ranges TBD.
