t1012: MODELS.md — live model leaderboard with success rates

[marcusquinn]

Summary

• Fixes supervisor-helper.sh syntax error (duplicate Phase 12 code from prior incomplete merge)
• Hardens generate-models-md.sh: adds --output argument guard, fixes weighted average SQL to handle missing score criteria
• Regenerates MODELS.md with latest pattern data (508 data points)

Verification (t1008 verify mode)

Prior PR #1305 was closed due to CodeRabbit review issues. This PR addresses:

1. Supervisor syntax error (CRITICAL): Removed orphaned duplicate code block at line 11049 that caused bash -n to fail. Verified: bash -n supervisor-helper.sh passes.
2. --output guard: --output without value now exits with error instead of crashing on set -u. Verified: generate-models-md.sh --output exits with error.
3. Weighted average SQL: Replaced fragile AVG(CASE...) * 4 with per-response subquery that correctly handles missing criteria via NULLIF divisor normalization.
4. Regen stamp on failure (dismissed): Stamp update is intentionally unconditional — it is a throttle, not a success tracker.

Test Results

• bash -n generate-models-md.sh — pass
• bash -n supervisor-helper.sh — pass
• shellcheck generate-models-md.sh — clean (SC1091 info only)
• generate-models-md.sh --quiet — generates valid MODELS.md
• generate-models-md.sh --output (no value) — correctly errors with guard
