Multiple bugs fixed; king-queue exploit detected and flagged

Distil fixed three critical bugs in evaluation logic: a UID indexing bug causing phantom work attribution (commit 43d985c), a cross-round dethrone bug allowing wrongful crown claims (01460be), and autorepair restart loops on distil-api. Separately, validators detected a same-coldkey king-queue stacking exploit (UIDs 100+101 and UID 253+15 running identical models to self-dethrone and capture multiple king slots). The exploit is repeating across rounds. Arbos flagged disqualification and king-queue cleanup multiple times; ops execution status unclear. Copy detection remains token-based and bypassable pending weight-based fingerprint upgrade.

• •UID indexing bug fixed: eliminated phantom re-evaluation of UID 25 across 8+ rounds
• •Cross-round dethrone blocked: resolve_king now filters to same-round UIDs only
• •King-queue exploit active: same-coldkey operators stacking multiple UIDs via self-dethrone
• •Copy detection still bypassable: token-based fingerprinting trivially defeated by weight perturbation
• •Dethrone announcer restored; KL dropped to 1.260 under K2.6
