fix: Install golangci-lint from source for Go 1.25 compatibility

The golangci-lint-action uses pre-built binaries that were compiled
with Go 1.24, which can't analyze code targeting Go 1.25.3.

Changed to install golangci-lint from source using the Go 1.25
environment, which ensures compatibility with the project's Go version.

Fixes lint error: 'the Go language version (go1.24) used to build
golangci-lint is lower than the targeted Go version (1.25.3)'
