Port of 0903pr46 e100a95: - gate the VMILoadOp natural-layout seed on packed-carrier/8-bit rules, leave other loads unconstrained so consumer deinterleaved requests (e.g. channel_split) still propagate back to the load - restrict {8->32 ls(4) c()} preferred cast row and {8->32 ls(2) d(2)} legal cast row to packed carriers / integer casts - restore dense 8-bit extf factor-4 requirement in VMIToVPTO - update e2b group-broadcast lit expectations to contiguous fallback

Co-authored-by: zoujiangjiang<zoujiangjiang@h-partners.com> # message auto-generated for no-merge-commit merge: !53 merge fix/vmi-patch-context-new into master fix: update VMI patch context for requires-python change Created-by: zoujiangjiang Commit-by: zoujiangjiang Merged-by: cann-robot Description: ## 问题 master 上代码同步提交（394bb77a）将根目录 pyproject.toml 的 requires-python 从 >=3.10 改为 >=3.7，导致 packaging/ptoas-vmi/pyproject.toml.patch 的 hunk 1 上下文失配，git apply 失败： ``` error: patch failed: pyproject.toml:18 error: pyproject.toml: patch does not apply ``` vmi-source-patch-check（Validate VMI source patch）随之失败，阻塞所有 PR 的 CI。GitHub 侧 hw-native-sys/PTOAS 同样受影响（见 PR #1473 的 vmi-source-patch-check job）。 ## 修复 仅修改 patch 文件中一行上下文：requires-python = ">=3.10" → ">=3.7"，与当前 master 的 pyproject.toml 对齐。 ## 验证 本地以 CI 同款方式验证通过： ``` python packaging/ptoas-vmi/prepare_source.py --output-dir .work/ptoas-vmi-source-check --revision HEAD # EXIT=0，打补丁后 pyproject.toml 含 ptoas-vmi / 0.1.6 / >=3.7 / sdist.inclusion-mode / PTOAS_CLI_VERSION_LABEL ``` See merge request: cann/pto-as!53
