Subject: [PATCH] fix(build): add missing fmt import to a2a_proxy.go
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Build broken on main since d86b8fe — a2a_proxy.go uses fmt.Errorf()
(8 call sites) but the import was dropped during an isSafeURL refactor
merge. CI fails with "undefined: fmt" at lines 743-775.
