Module pyth 

Pyth Hermes pull-feed helpers (PriceUpdateV2 accounts).

Replaces the legacy pyth-sdk-solana push-oracle dependency. Price update accounts are posted on-chain by the executor crank just before each oracle-gated instruction by calling the Pyth Receiver program (PYTH_RECEIVER_PROGRAM). This module reads them directly via borsh deserialization (no anchor-lang dependency required).

Flow

1. Executor fetches signed price update VAA from Hermes REST API.
2. Executor posts it via PYTH_RECEIVER_PROGRAM::post_update → PriceUpdateV2 account.
3. Executor calls our instruction with that account as pyth_price_feed_info.
4. Program validates owner, feed ID, staleness, then reads price.
