Capture cross-platform startup, SSH credentials, preview packaging gates, and current SSH, answer-reader, math, and icon work. Remove unrelated product comparisons from public source comments. Preview helper and shell tests pass locally. Native macOS/Linux build, test, and package validation remain pending in CI. Local Windows-only hooks cannot execute under WSL; content and workflow checks were run separately.

"""平台 cfg 预算：`nebula_app/src/platform/` 之外的平台 `cfg` 只能减不能增。
|
||
|
||
三端一致性的编译门。平台差异应收进 `platform/`（能力表 + 每平台实现），
|
||
业务代码写 `if CAPABILITIES.xxx` 而不是 `#[cfg(windows)]`。基线数字写在
|
||
`scripts/platform_cfg_budget.txt`：超预算失败；低于预算时提示把数字收紧，
|
||
和 guardrails 的其他预算一样，报「少于预算」就照报告改数字。

用法：python3 scripts/check_platform_cfg.py [--update]
