v0.2.0

Minor Changes

• d843e36: add readPlan, readSubscription, and readJob on MolphaSolanaClient

  On-chain read helpers for plan, subscription, and job accounts (nullable, like
  readFeed). getPlan now delegates to readPlan and throws when missing.

• 4e48226: make subscription payment explicit on subscribe/extendSubscription

  subscribe and extendSubscription now require a maxPriceUsdc confirmation
  (USDC base units) so callers explicitly acknowledge the on-chain USDC charge.
  The SDK reads the live plan price and aborts before sending the transaction if
  it exceeds the confirmed maximum, and returns the amount charged as pricePaid.
  Added getPlan(plan) to fetch the current price/terms for display beforehand.

Patch Changes

• 8f90138: require maxPriceUsdc confirmation for subscribe/extend

• 48878d9: align deriveApiConfigHash with node hashing (keccak256(JSON.stringify(canonicalApiConfig)))

  API config hashing now matches node-side verification by hashing the canonicalized
  config JSON string directly (with SDK defaults applied), instead of JCS.

• 41b0816: simplify sdk init, add api-config hasher
