Fix environment pointer invalidation in TShellCommand2026-07-18T11:20:59Zilikepugsilikepugs@yandex-team.com2026-07-18T09:52:18Zurn:sha1:94a1a2d91ceb33eed9e90ccf64804ce0d965dd33
TShellCommand built the environment array by storing pointers to strings while simultaneously appending those strings to a vector.
When the vector reallocated, short strings using SSO were moved together with their inline storage. Previously stored pointers could therefore become dangling and cause environment variables passed to the child process to be corrupted or lost.
Build all environment strings first and only then create the pointer array passed to execve. This ensures that the underlying string storage remains stable for the lifetime of the pointer array.

ysaveload.h: adjust sorted container insert hint2026-07-09T17:29:55Zswarmerswarmer@yandex-team.com2026-07-09T17:00:29Zurn:sha1:d7c6993ed0ed0ce2a53642b7b72f4be73523e11e
> The hint should point just after the element to be inserted. The container tries to place the new value just prior to the hint.

TIntrusiveList: add move ctor and move assignment operator for items2026-07-07T22:33:37Zswarmerswarmer@yandex-team.com2026-07-07T22:03:54Zurn:sha1:b16b689134145b52a37f464631fd470a92098468
The constructor and move operator allow the use of classes with TIntrusiveListItem in any container, not just node-based ones. For example, it is now possible to link vector elements to a TIntrusiveList.

Use trivial_abi in THolder2026-07-06T17:51:08Zswarmerswarmer@yandex-team.com2026-07-06T17:16:10Zurn:sha1:c0103a765a3d969af6adebc562976fefe3e2cd41
Apply trivial_abi to THolder so it can be passed directly in registers instead of through an invisible reference to caller-allocated memory.
