fix(sse): preserve auto scoring order

[jacobsparts]

Problem

Auto routing already includes task fitness as one of its scoring criteria. Running the separate generic task-aware reorder afterward scored task fit a second time and could overwrite the final order produced by the full auto score.

Summary

• Stop generic task-aware post-processing from reordering targets after auto routing has completed scoring.
• The task-routing predicate no longer classifies auto as a generic task strategy; explicit task strategies retain their behavior.

Related Issues

• Related to 🔴 Release branch not green: release/v3.8.50 #9985 (inherited release/v3.8.50 base status; not caused by this patch)

Validation

• Change type: routing
• Focused regression test passed
• Focused category gates from the Contribution Golden Path
• npm run lint
• Reconciled with the current active release base; focused checks rerun afterward
• Production-code changes include a new or updated automated test in this PR

This is a draft. Final category-gate and lint results will be recorded before review.

Tests Added Or Updated

• tests/unit/combo-task-aware.test.ts

Coverage Notes

• The updated regression verifies that auto bypasses generic task reordering while explicit task strategies remain eligible.
• No known touched-file coverage decrease.

Reviewer Notes

• Task fitness is not removed: it remains part of auto candidate scoring.
• Explicit task-aware strategies retain their existing post-processing behavior.
• The optional taskFit=0 defense is excluded because it would broaden semantics without a demonstrated regression.
