Summary
Pins the Go toolchain to 1.26.4 in `go.mod` to fix three stdlib CVEs introduced since go1.26.3:
This is the clean fix. Once merged, the exclusions added in #5425 can be reverted and Renovate will handle future toolchain bumps automatically (the `toolchain` depType is enabled by default in the `gomod` manager).
