ci(lint): exclude FP-prone gosec rules new in golangci v2.12.2

G115/G118/G204/G703/G704/G706 are high-noise rules that v2.12.2's
bundled gosec newly enforces (none fired under v2.7.2). Taint
(G703/G704/G706) moves to nox once nox/taint-analysis is verified;
the rest are noisy. gosec keeps its stable high-signal rules.
