Removes the blanket GOTOOLCHAIN=local constraint that blocks Go
toolchain downloads in CI. The Konflux compatibility checks (PRs
#19737, #19024) now validate Go version compatibility in the actual
build environment, making this simulation unnecessary.

Changes:
- Makefile: Remove GOTOOLCHAIN=local enforcement, keep git diff check
- scanner/Makefile: Remove GOTOOLCHAIN=local enforcement, keep git diff check

The git diff check remains to ensure developers commit go mod tidy results.
Konflux checks will catch actual compatibility issues before merge.

Konflux now tracks upstream Go releases, eliminating the need for the
go-version-ceiling job that enforced maximum Go version compatibility.

This job was introduced in #19737 as a temporary measure until Konflux
caught up with Go releases. With Konflux's improved tracking, this
validation is no longer necessary.

Bumps Go from 1.26.1 to 1.26.2 to address critical compiler bugs
and security vulnerabilities fixed in the April 7, 2026 release:

- CVE-2026-33810: Compiler fails to unwrap pointers in no-op interface conversions
- CVE-2026-27144: Incorrect bounds checking for slices/arrays with induction variables
- CVE-2026-32282: html/template XSS vulnerability in JS template literals
- CVE-2026-27143: tar.Reader unbounded memory allocation

These compiler bugs in 1.26.1 were causing widespread test failures
in CI (unit tests, postgres tests, benchmarks). Go 1.26.2 includes
the necessary fixes for safe production use.

Updates Go version in all tool modules to match the main go.mod:
- tools/build/go.mod: 1.25.0 → 1.26.2
- tools/check-workflow-run/go.mod: 1.25 → 1.26.2
- tools/linters/go.mod: 1.25.0 → 1.26.2
- tools/proto/go.mod: 1.25.7 → 1.26.2
- tools/test/go.mod: 1.25 → 1.26.2

This fixes the golangci-lint CI failure where golangci-lint was built
with Go 1.25.0 but tried to lint code targeting Go 1.26.

Error was:
  can't load config: the Go language version (go1.25) used to build
  golangci-lint is lower than the targeted Go version (1.26)

Fixes govet printf errors caught by Go 1.26.2:
- pkg/env/integersetting.go: Use %v instead of %q for []int slice
- pkg/grpc/testutils.go: Add ... when forwarding variadic args

Disables modernize linter (373 instances):
- The modernize linter suggests using Go 1.26's new(expr) syntax
- This is a large change (373 files) better suited for a separate PR
- TODO ROX-34147: Re-enable in follow-up PR for code modernization
