[BUG] USDC payment events silently ignored - rule engine only processes XLM

[thisisouvik]

Description

In processor.ts, the doesPaymentMatchTrigger() function hard-codes isXLM and returns false for any USDC payment. Users who receive USDC will have no rules triggered even for a generic rule. The depositUSDCToVault() function in vault.ts exists but is never called by the engine.

Root Cause

processor.ts line 42: "return matchesTrigger and isXLM" -- USDC payments always evaluate to false.

Steps to Reproduce

1. Create an automation rule for saving a percentage of payments.
2. Receive USDC to the monitored wallet.
3. Observe that no automated transaction is created.

Impact

High - USDC is one of the most common assets on Stellar. AutoPilot silently ignores all USDC payment events.
