Bump ver 2

[Overtorment]

Note

Add SilentPayment.detectOurUtxosUsingTweakbscanBspend and tests for detecting incoming payments using either seed or tweak+bscan+Bspend.

• API:
  • Add SilentPayment.detectOurUtxosUsingTweakbscanBspend(tx, tweakHex, bscan, Bspend) in src/index.ts to detect owned p2tr UTXOs using a precomputed tweak and scan/spend keys (no wif derivation).
• Tests (tests/silent-payment.test.ts):
  • Split and expand detection tests:
    • "using seed" and "using tweak" variants for tx 511e00...a9cf and c0deee...50f9.
  • Verify outputs and utxoType for both detection paths.
  • Minor renames to clarify test intent.
