VerifyScript with transaction context for signature verification

This version includes the full transaction context needed for proper Script verification with transaction context and optional block height.

Pass block_height whenever it is known; height-dependent fork rules (CLTV, CSV, SegWit, Taproot) rely on it to select the correct evaluation path. Passing None falls back to height 0 inside the engine, which means pre-activation rules are used — valid only for regtest / test-vector scenarios.

For callers that also need to supply a pre-computed sighash or a specific SigVersion, use verify_script_with_context_full directly.
