Adds google/gemini-4-argon (Google's frontier reasoning model, live on Base and Solana since 2026-10-20 — blockrun#855, blockrun-sol#466) to the local catalog, the picker (top-models.json) and the README table.

• $2/$10 per 1M, 1M context, 65,536 max output, reasoning + vision + tools.
• Catalog only — no routing tier, profile or default picks it.
• Without the entry, estimateAmount() returns undefined for the id: the balance check is skipped and maxCostPerRun projects $0.
• ⏰ Google reprices to $4/$20 on 2026-12-01; dated note in the entry.
• @blockrun/model-catalog / router-core pins are unchanged here; they are being updated separately.

Tests: vitest 1220 passed (one unrelated proxy.solana-batch deadline test flaked under full-suite load; passes 3/3 alone, with and without this change). tsc --noEmit and eslint src/ clean. npm run build + dist smoke check pass.

Merge Risk: 🟡 Moderate · up to b5ae0

Gemini 4 Argon is priced at its introductory rate with no date-aware switch. After December 1, 2026, cost estimates and per-run spending caps could understate the real $4/$20 cost on installed releases. Use the existing date-aware pricing mechanism, or confirm a follow-up release before then.

🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy lift

Apply the scheduled price change in cost estimates.

If a user keeps this release installed on December 1, 2026, inputPrice and outputPrice remain at $2/$10 while Google's published rates become $4/$20. estimateAmount() will then understate Argon costs, and maxCostPerRun can permit a request that exceeds its configured cap. A dated comment cannot update an installed release. Make the effective rates date-aware in the cost calculation, or use another mechanism that preserves the cap when the introductory rate ends.
