fix: migrate goreleaser from v1 to v2 to fix Go 1.25+ build failure

Goreleaser v1.x depends on golang.org/x/tools v0.8.0-v0.25.0,
which fail to compile with Go 1.25+ due to stricter constant
evaluation (golang/go#74462).

Migrate to goreleaser v2.15.4 which uses x/tools v0.44.0.

Config changes for v2:
- Add version: 2 header
- archives.builds -> archives.ids
- archives.format -> archives.formats (list syntax)
