Pull Request Overview

This PR fixes a use-after-free issue in the CPU scheduler, addresses a verify failure in the CPU limiter, and updates handling of resource weight in the node service.

• Fix CPU limiter verification by normalizing AmountCPULimit near zero.
• Refactor resource weight handling in the compute scheduler and node service for safety and clarity.

Reviewed Changes

Copilot reviewed 3 out of 3 changed files in this pull request and generated no comments.

File	Description
ydb/core/tx/conveyor/service/service.cpp	Adds a check to reset AmountCPULimit to zero when near zero to prevent verify failures.
ydb/core/kqp/runtime/kqp_compute_scheduler.cpp	Refactors resource weight check by caching the Enabled() call and loops through Params until fully purged.
ydb/core/kqp/node_service/kqp_node_service.cpp	Adds an extra check with HasResourceWeight() to safely assign resource weight from the message.
