VerifyScript with full context including block height, median time-past, and network

This version includes block height, median time-past, and network needed for proper BIP65 (CLTV), BIP112 (CSV), BIP66 (Strict DER), and BIP147 (NULLDUMMY) validation.

Arguments

• block_height - Optional current block height (required for block-height CLTV, BIP66, BIP147)
• median_time_past - Optional median time-past (required for timestamp CLTV per BIP113)
• network - Network type (required for BIP66 and BIP147 activation heights) VerifyScript with full context - optimized version using parallel slices

This version accepts prevout values and script_pubkeys as separate slices to avoid unnecessary cloning of script_pubkey data. P2PK fast-path. Bare pay-to-pubkey: scriptPubKey is pubkey + OP_CHECKSIG, scriptSig is sig. Common in early blocks (coinbase outputs). Returns Some(Ok(bool)) if handled; None to fall back.
