fix: enforce fresh nightly promotion quality gates
Ensure promotion decisions are based on current nightly HEAD evidence instead of stale workflow history.
Add native CodeQL branch triggers so security analysis runs on nightly/main promotion paths.
Convert nightly and weekly automation to dispatch required checks only when missing for the exact HEAD commit, preventing duplicate/racing runs while guaranteeing check presence.
Harden weekly health verification with retry polling so transient scheduling delays do not produce false negatives.
This reduces false blocking and ensures nightly-to-main promotion uses current, deterministic CI state.
