Fans security fix from internal#116. Same rationale: pull_request loads workflow from PR HEAD; pull_request_target loads from base (main). Verified on internal canary — synthetic exfil-attempt did NOT execute.

fix(sop-tier-check): use pull_request_target — pull_request leaks token 5fe335ffae 
Fans the security fix from internal#116 (cce89067) to molecule-core. Same
rationale: pull_request loads workflow from PR HEAD, allowing any
write-access contributor to rewrite the workflow file in their PR and
exfiltrate SOP_TIER_CHECK_TOKEN. pull_request_target loads from base
(main), neutralising the attack.

Verified post-merge on internal: synthetic PR rewriting the workflow to
print the token did NOT execute the modified version — main's
pull_request_target version ran instead. ATTACK_PROBE never fired.
