Commit Message

silentpayments: add cross-implementation edge case tests

Add test cases distilled from comparing this package against the
BIP-0352 reference implementation, the secp256k1 silentpayments module
and independent Go/Rust scanners:

  - Annex handling: the annex is any last witness element whose first
    byte is 0x50, not only a single-byte 0x50 element (a divergence
    found in other implementations). Mishandling it shifts which
    element is treated as the control block and bypasses the NUMS
    internal key skip.

  - Smallest-outpoint selection: the outpoint is compared in its
    serialized little-endian form, so for the same txid, vout 256
    sorts before vout 1. An integer comparison would produce a
    valid-looking but wrong input hash and silently break
    sender/receiver agreement.
