Code Review

This pull request aims to update the Go version in go.mod to address a security vulnerability (GO-2025-4155). However, the specified version 1.25.5 appears to be a typo as Go 1.25 is not a released version, which will cause build failures. More critically, the current build infrastructure, particularly hack/install-go.sh, does not enforce the go.mod version, potentially leading to the project being built with a vulnerable toolchain. Additionally, the installation script and Makefile contain unquoted variables that could introduce command injection vulnerabilities, though these were not introduced in this PR.

[gemini-code-assist]

The update to Go version 1.25.5 is intended to fix a security vulnerability (GO-2025-4155). However, 1.25.5 is not a released Go version and appears to be a typo, which will cause build failures. More critically, the project's build process is currently configured in a way that makes this fix non-deterministic. The hack/install-go.sh script (called by the Makefile) dynamically fetches the latest Go version from the internet (https://go.dev/dl/?mode=json) instead of respecting the version specified here in go.mod. This means that the actual Go toolchain used to build the project may not match the version declared in this file. If the external API returns an older version, the resulting binaries will remain vulnerable to GO-2025-4155. To remediate this, correct the Go version to a released, secure version (e.g., 1.22.5) and update hack/install-go.sh to extract the Go version directly from go.mod using a command like grep "^go " go.mod | cut -d' ' -f2.
