Bump golang.org/x/net from v0.49.0 to v0.55.0 across all four go.mod files to remediate CVE-2026-27136 (XSS via HTML parsing bypass in golang.org/x/net/html). This also resolves: - GO-2026-5026: Punycode label validation bypass in x/net/idna - GO-2026-4918: HTTP/2 infinite loop (module-level fix; stdlib still requires Go compiler upgrade) Affected go.mod files: - go.mod - documentation/examples/remote_storage/go.mod - internal/tools/go.mod - web/ui/mantine-ui/src/promql/tools/go.mod Resolves: ACM-36866 Signed-off-by: Coleen Iona Quadros <coleen.quadros27@gmail.com>
