Update dependency tsec to ^0.2.0

Editor assessment

A clean dependency bump: `build: update dependency tsec to ^0.2.0` names the exact package and version range, making the change fully understandable without a diff. The absent body is appropriate for a routine tooling bump, which the rubric exempts for small changes. The `PR Close #44274` footer is well formed and is the only trailer present, which is all that is needed. Style hygiene is excellent — imperative verb, no trailing period, compact subject, no ticket junk, consistent language. Teaching value is inherently minimal because there is nothing to explain, but the message is clear, correct, and self-sufficient at the good level.
