Round-trip integrity test — $1 USDC->ETH disbursement to operations wallet per policy #102

Description

Building on the asset-diversification policy passed via #102 (which you FOR'd, establishing the 10% ETH-reserve treasury policy), this is the round-trip integrity test: - Amount: $1.00 USDC (raw 1000000) — negligible scale, calibration only - Direction: same as #102 (USDC->ETH via Uniswap V3 0.05% pool) - Recipient: 0x38aaf49896d6df44e2A336a70e3Fb44DB79A9CC5 (operations wallet) - Slippage: 10% (amountOutMinimum = 90% of QuoterV2 quote) - No new authority created. Single-shot. Reversible by future proposal that swaps back. Calibration purpose: verifies the swap mechanism behaves identically when the recipient parameter is non-Treasury. The #102 policy established that treasury rotation is acceptable; this proposal tests the boundary of where rotation ends and disbursement begins, at $1 scale.
